Description

The present invention relates to a mass spectrometer.

Mass spectrometers are known as analytical devices that analyze the masses of components contained in a sample. For example, Patent Document 1 describes a time-of-flight mass spectrometer. In this mass spectrometer, ions are generated from a sample in a chamber. The generated ions are accelerated by an electric field, fly through a high vacuum part in the chamber, and reach an ion detector. The flight time of the ions at this time varies depending on the mass-to-charge ratio of the ions. Therefore, the mass-to-charge ratio of each ion is measured based on the flight time of the accelerated ions until they are detected by the detector.
International Publication No. 2017/060991

In preparation for starting mass analysis, the vacuum pump is started. This causes the chamber to be evacuated after a predetermined time. After the chamber has been evacuated, analysis parameters corresponding to the analysis conditions for performing any mass analysis are set in the mass analyzer. This causes control of the components of the mass analyzer to begin based on the set analysis parameters. After a predetermined time, the analysis conditions are satisfied, making it possible to start mass analysis.

This kind of preparation before starting mass analysis must be done every time the mass spectrometer is started. This places an increased burden on the user. In addition, the waiting time before mass analysis can be started becomes longer. As a result, the usability of the mass spectrometer is reduced.

The object of the present invention is to provide a mass spectrometer with improved usability.

One aspect of the present invention relates to a mass spectrometer comprising an analysis unit that performs mass analysis of a sample based on analysis parameters corresponding to analysis conditions, a start-up switch, a read-out unit that reads out previously set analysis parameters or analysis parameters previously specified by a user in response to the start-up switch being turned on, a setting unit that sets the analysis parameters read out by the read-out unit, and a start-up unit that starts up the analysis unit in accordance with the analysis parameters set by the setting unit.

The present invention makes it possible to improve the usability of a mass spectrometer.

(1) Configuration of the Analysis System A mass spectrometer according to an embodiment of the present invention will now be described in detail with reference to the drawings. Fig. 1 is a diagram showing the configuration of an analysis system including a mass spectrometer according to an embodiment of the present invention. As shown in Fig. 1, the analysis system 200 includes a mass spectrometer 100, a chromatograph 210, a processing device 220, an operation unit 230, and a display unit 240.

In this example, the chromatograph 210 is a liquid chromatograph. In the chromatograph 210, the sample to be analyzed is introduced into a separation column together with a solvent. The sample introduced into the separation column is separated into components based on differences in chemical properties or composition. The liquid sample separated into components is introduced into the mass spectrometer 100, where mass analysis of the sample is performed. Details of the mass spectrometer 100 will be described later.

The processing device 220 is realized by an information processing device such as a personal computer, and includes a CPU (central processing unit) and a storage device. The processing device 220 issues control commands to the mass spectrometer 100 or the chromatograph 210. The processing device 220 also processes the analysis results by the mass spectrometer 100 or the chromatograph 210 to generate a mass spectrum or a chromatogram, etc.

The operation unit 230 is an input device such as a keyboard, mouse, or touch panel. A user can issue various instructions to the processing device 220 by operating the operation unit 230. The display unit 240 is a display device such as a liquid crystal display device. The display unit 240 can display mass spectra or chromatograms generated by the processing device 220.

(2) Mass Spectrometer Figure 2 is a schematic diagram showing the configuration of the mass spectrometer 100 of Figure 1. As shown in Figure 2, the mass spectrometer 100 includes an analysis section 110, a vacuum pump 120, a power supply unit 130, a control unit 140, and a housing unit 150. The mass spectrometer 100 is also provided with gas supply units 101-104. The analysis section 110 includes a vacuum vessel 10, an ion source 111, ion guides 112-114, a mass filter 115, a collision cell 116, a mass filter 117, and a detector 118, and performs mass analysis of a sample based on set analysis parameters.

The vacuum vessel 10 extends in the direction in which ions fly. In the following description, the direction in which ions fly in the vacuum vessel 10 is defined as downstream, and the opposite direction is defined as upstream. In the vacuum vessel 10, an ionization chamber 11, a vacuum chamber 12, a vacuum chamber 13, a vacuum chamber 14, and a vacuum chamber 15 are provided in the vacuum vessel 10, arranged in this order from upstream to downstream. The degree of vacuum in the vacuum vessel 10 increases from upstream to downstream. Therefore, the degree of vacuum in the ionization chamber 11 is the lowest, and the degree of vacuum in the vacuum chamber 15 is the highest. For example, the pressure in the ionization chamber 11 is approximately atmospheric pressure, and the pressure in the vacuum chamber 15 is 10 ⁻² to 10 ⁻³ Pa.

The ionization chamber 11 and the vacuum chamber 12 are separated by a partition 20. A DL (desolvation line) 21 is provided in the partition 20. The ionization chamber 11 is adjusted to a predetermined temperature by a heater 1. The vacuum chamber 12 and the vacuum chamber 13 are separated by a partition 30. A skimmer cone 31 is provided in the partition 30. The vacuum chamber 13 and the vacuum chamber 14 are separated by a partition 40. A hole 41 is provided in the partition 40. The vacuum chamber 14 and the vacuum chamber 15 are separated by a partition 50. A hole 51 is provided in the partition 50.

The ion source 111 includes an ionization probe, such as an ESI (Electrospray Ionization) probe, and is attached to the ionization chamber 11. A liquid sample separated into its components by the chromatograph 210 in FIG. 1 is supplied to the ion source 111. A nebulizer gas, such as nitrogen gas, is also supplied to the ion source 111 by the gas supply unit 101. By supplying the nebulizer gas to the ion source 111, the sample is sprayed in the ionization chamber 11 while being charged.

Furthermore, a heating gas such as clean air is supplied to the ion source 111 by the gas supply unit 102. The ion source 111 is also provided with a heater 2 that heats the heating gas. The sample to be sprayed is heated by supplying the heating gas to the ion source 111. As a result, the components in the sprayed sample are ionized in the ionization chamber 11. Usually, singly charged ions of each component are generated.

A drying gas such as clean air is supplied to the ionization chamber 11 by the gas supply unit 103 so that it flows from downstream to upstream. By supplying the drying gas to the ionization chamber 11, neutral molecules and non-measurement ions are removed from the ions generated in the ionization chamber 11.

The ion guides 112-114 are arranged in the vacuum chambers 12-14, respectively. Ions generated in the ionization chamber 11 are guided to the vacuum chamber 12 through the DL 21 of the partition 20. The DL 21 is provided with a heater 3 for heating the ions. This removes droplets associated with the ions. The ions that reach the vacuum chamber 12 are guided by the ion guide 112 through the skimmer cone 31 of the partition 30 to the vacuum chamber 13. The ions that reach the vacuum chamber 13 are guided by the ion guide 113 through the hole 41 of the partition 40 to the vacuum chamber 14. The ions that reach the vacuum chamber 14 are guided by the ion guide 114 through the hole 51 of the partition 50 to the vacuum chamber 15.

The mass filter 115, collision cell 116 and mass filter 117 are arranged in the vacuum chamber 15 in this order from upstream to downstream. Each of the mass filters 115 and 117 is, for example, a quadrupole mass filter including four rod electrodes. The mass filter 115 allows only ions that have a specific mass-to-charge ratio corresponding to the applied voltage to fly through the ions that reach the vacuum chamber 15. The ions that pass through the mass filter 115 reach the collision cell 116 as precursor ions.

A collision-induced dissociation (CID) gas such as argon gas is supplied to the collision cell 116 by the gas supply unit 104. In the collision cell 116, the precursor ions collide with the CID gas, dissociating the precursor ions to generate product ions. The mass filter 117 allows only precursor ions having a specific mass-to-charge ratio corresponding to the applied voltage to fly and pass through the precursor ions generated in the collision cell 116.

The detector 118 is, for example, an electron multiplier, and is disposed in the vacuum chamber 15 so as to be located downstream of the mass filter 117. The detector 118 detects ions that have passed through the mass filter 117, and provides a detection signal indicating the amount of detection to the control device 140 as the analysis result.

The vacuum pump 120 includes, for example, a rotary pump and a turbo molecular pump, and maintains each of the vacuum chambers 12-15 at a predetermined vacuum level by evacuating the atmosphere in the vacuum chambers 12-15. The power supply unit 130 includes an amplifier, a switch, etc., and supplies high voltage to each part of the analysis unit 110, including the mass filters 115 and 117. The power supply unit 130 is also provided with a heater 4 for adjusting the temperature to a constant level.

The control device 140 includes, for example, a CPU and a storage device. When the analysis unit 110 is started, the control device 140 starts the operation of the vacuum pump 120 and sets analysis parameters corresponding to the analysis conditions for performing mass analysis. The power supply unit 130, heaters 1-4, and gas supply units 101-104 operate based on the set parameters. During mass analysis, the control device 140 also controls the operation of the analysis unit 110 based on a control command from the processing unit 220 in FIG. 1. Furthermore, the control device 140 provides the analysis results by the analysis unit 110 to the processing unit 220. Details of the control device 140 will be described later.

The housing unit 150 houses the analysis unit 110, the vacuum pump 120, the power supply unit 130 and the control unit 140. In the example of FIG. 2, the gas supply units 101-104 are arranged inside the housing unit 150, but some or all of the gas supply units 101-104 may be arranged outside the housing unit 150. The housing unit 150 is provided with a main power switch 151 and a start switch 152. The start switch 152 is arranged on the front surface of the housing unit 150 where it can be easily operated by the user. The main power switch 151 is arranged on the rear surface of the housing unit 150, opposite the front surface.

The control device 140 is started up when the main power switch 151 is turned on. With the main power switch 151 on, the analysis unit 110 is started up when the start-up switch 152 is turned on. In this embodiment, the start-up switch 152 is a physical switch, but it may be a GUI (Graphical User Interface) displayed on a display screen or the like. In addition, if the start-up switch 152 also has the function of the main power switch 151, the main power switch 151 does not need to be provided.

(3) Control Device Fig. 3 is a block diagram showing the configuration of the control device 140 in Fig. 2. As shown in Fig. 3, the control device 140 includes, as functional units, a storage unit 141, a readout unit 142, a pump control unit 143, a reception unit 144, a setting unit 145, a startup unit 146, and an analysis execution unit 147. The functional units of the control device 140 are realized by the CPU of the control device 140 executing a mass spectrometry control program stored in the storage device. Some or all of the functional units of the control device 140 may be realized by hardware such as electronic circuits.

The storage unit 141 stores the analysis parameters previously set by the setting unit 145. In this example, the storage unit 141 stores the analysis parameters set each time the analysis parameters are set by the setting unit 145. In this case, the storage unit 141 stores the analysis parameters that were set by the setting unit 145 at the end of the previous mass analysis.

The readout unit 142 reads out the analysis parameters stored in the storage unit 141 in response to the start switch 152 being turned on. The pump control unit 143 starts the operation of the vacuum pump 120 in response to the start switch 152 being turned on.

Here, in routine work, mass spectrometry may be performed based on the same analysis parameters as those previously set. On the other hand, the analysis parameters previously set may not be the analysis parameters desired by the user. Thus, the reception unit 144 receives an instruction for analysis parameters from the processing device 220. If the analysis parameters stored in the storage unit 141 are not the desired analysis parameters, the user can instruct the processing device 220 to specify the desired analysis parameters by operating the operation unit 230 in FIG. 1.

The setting unit 145 sets the analysis parameters read by the reading unit 142. Furthermore, when an analysis parameter is specified by the reception unit 144, the setting unit 145 updates the set analysis parameter to the specified analysis parameter. Furthermore, each time an analysis parameter is set, the setting unit 145 stores the set analysis parameter in the storage unit 141.

The startup unit 146 starts the analysis unit 110 in accordance with the analysis parameters set by the setting unit 145. Specifically, the analysis parameters include temperature, gas, or voltage. The startup unit 146 starts the operation of the heaters 1 to 4 so that the heaters 1 to 4 operate at the set temperature. The startup unit 146 starts the operation of the gas supply units 101 to 104 so that the set gas is supplied. The startup unit 146 starts the operation of the power supply device 130 so that the set voltage is supplied to each part of the analysis unit 110.

The analysis execution unit 147 controls the operation of the analysis unit 110 so that mass analysis is performed based on a control command given by the processing unit 220. When an instruction to start mass analysis is given by the user via the operation unit 230, the processing unit 220 gives a control command to execute mass analysis to the analysis execution unit 147. In addition, the analysis execution unit 147 acquires the analysis results from the analysis unit 110 and provides the acquired analysis results to the processing unit 220. As a result, a chromatogram or the like is generated in the processing unit 220.

(4) Mass spectrometry control process Figure 4 is a flowchart showing an algorithm of the mass spectrometry control process by the control device 140 of Figure 3. The mass spectrometry control process of Figure 4 is performed by the CPU of the control device 140 executing a mass spectrometry control program stored in the storage device. The mass spectrometry control process will be described below with reference to the flowchart of Figure 4 together with the control device 140 of Figure 3.

First, the readout unit 142 determines whether the start-up switch 152 is turned on (step S1). If the start-up switch 152 is not turned on, the readout unit 142 waits until the start-up switch 152 is turned on. If the start-up switch 152 is turned on, the readout unit 142 reads out the analysis parameters stored in the storage unit 141 (step S2). In addition, the pump control unit 143 starts the operation of the vacuum pump 120 (step S3).

In this example, step S3 is executed between step S2 and the next step S4, but the embodiment is not limited to this. Step S3 may be executed simultaneously with step S2 or step S4. Alternatively, step S3 may be executed after step S4 or before step S2. When step S3 is executed before step S2, step S1 may be executed by the pump control unit 143.

Next, the setting unit 145 sets the analysis parameters read out in step S2 (step S4). The setting unit 145 then stores the set analysis parameters in the storage unit 141 (step S5). Next, the startup unit 146 starts up the analysis unit 110 in accordance with the analysis parameters set in step S4 (step S6). This causes heaters 1 to 4 to operate at the set temperature. In addition, the set gas is supplied by the gas supply units 101 to 104. In addition, the set voltage is supplied to each part of the analysis unit 110 by the power supply device 130.

Then, the analysis execution unit 147 judges whether or not the start of mass analysis has been instructed by the processing device 220 (step S7). If the start of mass analysis has not been instructed, the reception unit 144 judges whether or not an instruction for analysis parameters has been received from the processing device 220 (step S8). If an instruction for analysis parameters has not been received, the reception unit 144 returns to step S7. If an instruction for analysis parameters has been received, the setting unit 145 updates the analysis parameters set in step S4 to the instructed analysis parameters (step S9) and returns to step S5. As a result, the newly set analysis parameters are stored in the storage unit 141 in step S5. In addition, the analysis unit 110 is started according to the newly set analysis parameters.

When the start of mass analysis is instructed in step S7, the analysis execution unit 147 executes mass analysis by controlling the analysis unit 110 according to the control command given by the processing unit 220 (step S10). As a result, the analysis result by the analysis unit 110 is given to the processing unit 220, and the mass analysis control process ends.

(5) Effects In mass spectrometer 100 according to this embodiment, in response to start-up switch 152 being turned on, previously set analysis parameters are read out by read-out unit 142. The analysis parameters read out by read-out unit 142 are set by setting unit 145. Analysis unit 110 is started by start-up unit 146 in accordance with the analysis parameters set by setting unit 145. Furthermore, in response to start-up switch 152 being turned on, operation of vacuum pump 120 is initiated by pump control unit 143.

According to this configuration, in response to the start switch 152 being turned on, the analysis unit 110 is started according to the previously set analysis parameters, and evacuation of the vacuum vessel 10 is started. In this case, after turning on the start switch 152, the user does not need to perform any operation to set the analysis parameters, and does not need to perform any operation to operate the vacuum pump 120. This reduces the burden on the user.

Furthermore, when the analysis unit 110 is started, the heaters 1-4, gas supply units 101-104, and power supply unit 130 operate according to the set analysis parameters. This reduces the time required for temperature adjustment, the time required for gas supply, and the time required for voltage supply. In other words, the waiting time until mass analysis can begin is reduced. As a result, the usability of the mass analysis device is improved.

In addition, in this embodiment, each time the analysis parameters are set by the setting unit 145, the set analysis parameters are automatically saved in the storage unit 141. This allows the analysis unit 110 to be started according to the analysis parameters that were set at the end of the previous mass analysis each time the start switch 152 is turned on.

Furthermore, when analysis parameters are specified in the reception unit 144, the set analysis parameters are updated to the specified analysis parameters. Therefore, even if the analysis parameters set when the analysis unit 110 is started are not the analysis parameters desired by the user, the user can change the analysis parameters to be set during mass analysis to the desired analysis parameters.

(6) Other Embodiments (a) In the above embodiment, previously set analysis parameters are stored in storage unit 141, but the embodiment is not limited to this. The user can specify any analysis parameters to reception unit 144. Therefore, the analysis parameters specified by the user may be stored in storage unit 141. In this case, in response to start-up switch 152 being turned on, the analysis parameters specified by the user are read out. As a result, the analysis parameters specified by the user are set.

(b) In the above embodiment, each time an analysis parameter is set by the setting unit 145, the set analysis parameter is stored in the storage unit 141, but the embodiment is not limited to this. The user can instruct the reception unit 144 whether or not to store the analysis parameter. Therefore, in response to the user's instruction, the set analysis parameter may be stored in the storage unit 141. In this case, the user can store the desired analysis parameter that was previously set. Thereby, each time the start switch 152 is turned on, the analysis unit 110 can be started according to any analysis parameter that was previously set.

(c) In the above embodiment, the control device 140 includes the pump control unit 143, but the embodiment is not limited to this. The user may manually start the operation of the vacuum pump 120 after turning on the start switch 152. In this case, the control device 140 does not need to include the pump control unit 143.

(d) In the above embodiment, temperature adjustment, gas supply, and voltage supply are performed when the analysis unit 110 is started up, but the embodiment is not limited to this. When the analysis unit 110 is started up, only any one of temperature adjustment, gas supply, and voltage supply may be performed. For example, the time required for temperature adjustment tends to be longer than the time required for gas supply and the time required for voltage supply. Therefore, when the analysis unit 110 is started up, only temperature adjustment may be performed. In this case, gas supply and voltage supply are performed after the temperature adjustment is completed.

(e) In the above embodiment, the mass spectrometer 100 is used in a state connected to the processing device 220, but the embodiment is not limited to this. If the control device 140 has the same functions as the processing device 220, the mass spectrometer 100 may be used without being connected to the processing device 220. That is, in the above embodiment, the mass spectrometer 100 is an online type device, but may also be a stand-alone type device.

In the above embodiment, the mass spectrometer 100 is a stand-alone device with respect to starting the analysis unit 110. That is, the analysis unit 110 can be started in response to a start command given from the processing device 220, but can also be started by turning on the start switch 152 even if a start command is not given from the processing device 220.
