Description

The present invention relates to an analytical data processing apparatus.

(Prior art) To obtain various information from a measured spectrum, use analysis data in a narrow wavelength or energy range that includes a peak that characterizes a sample, and manage and analyze the data for each spectral peak that characterizes the sample. It is more effective to do so. However, since the distribution range of the elemental spectrum is unknown in the unknown sample, it is impossible to preset the narrow measurement range including the necessary spectrum peak as described above. Therefore, conventionally, the measurement is performed over a wide range in a large step, and the narrow measurement range including a necessary spectrum peak is measured again in detail in a fine step based on the measurement result. However, such a method is inefficient because the measurement takes a long time.

(Problems to be Solved by the Invention) An object of the present invention is to efficiently collect and manage analytical data in a narrow wavelength or energy range including a spectrum peak required for a sample.

(Means for Solving the Problem) A means for storing all of a wide range of detailed analysis data, a means for displaying the analysis data, a means for instructing a registration range from the analysis data, and an instruction for all analysis data. A means for storing the analytical data of the registered range is provided in the analytical data processing device.

(Operation) Recently, the storage capacity of a storage medium has been further increased, and it has become possible to store all measurement data obtained by measuring a wide wavelength or energy range in fine steps. Due to such a background, the present invention provides measurement data obtained by performing measurement in fine steps in a wide measurement range from the beginning without performing preliminary measurement for investigating a measurement range in which a spectral peak that characterizes a sample is included. Stored in the storage device, after the measurement is completed, the measured data is taken out and displayed on the display device, and the measured data range of the spectral peak that characterizes the sample is registered and designated with reference to the displayed spectrum. By trying to manage the measurement data, it is intended to reduce the measurement time.

(Embodiment) FIG. 1 shows an embodiment of the present invention. In FIG.
Reference numeral 1 is an analyzer, and 2 is an interface for communicating signals between the analyzer 1 and the CPU 3. The CPU 3 controls the analyzer 1 and the measurement data processing. Reference numeral 4 is a memory for storing measurement data and the like, 5 is a display device for displaying the measurement data and the result, and 6 is a keyboard for inputting various data and commands to the CPU 3.

FIG. 2 shows a flow chart of the measurement operation. First, analysis conditions such as a range of wavelength or energy to be measured by the analyzer 1 and measurement steps are set (a). in this case,
For example, for elemental analysis of a sample, set the wavelength range in which the peaks of all the elements that may be contained in the sample appear in advance.
When such a prediction cannot be made, the entire measurement range in the analyzer is specified, and the measurement step (sampling wavelength interval, etc.) is determined in advance by the target analysis accuracy. Perform a wide range of measurements set above to obtain all spectral data (a). The obtained measurement data is stored in the memory 4 (c). At this point, the measurement ends and the measurement data is processed. All the spectra are displayed on the display device 5 (d), and as shown in FIG. 3A, the keyboard 1, the keyboard 6 is operated to display the spectra 1, 2, 3, etc. containing the spectrum peak data to be registered. Specify with the cursor (e). Divide the measurement data according to the above registration conditions,
Store the divided data in memory. If necessary, the stored registration data is displayed on the display device 5 for each spectrum peak as shown in FIG. 3B for analysis.

(Effects of the Invention) According to the present invention, all the measurement data in fine steps are measured and stored by the main measurement, and after the measurement, the preliminary measurement is performed by dividing and storing for each spectrum peak data that characterizes the sample. It became unnecessary and it became possible to shorten the measurement time.
