Abstract
The utility model relates to an interrupted flow device for an atomic fluorophotometer, comprising a sample introduction pipe 1, a reductant pipe 2, a waste liquid pipe 3, a sampling ring 4, a gas carrying pipe 5, a pipe passage 6 for connecting an atomizer, peristaltic pumps 7, 8, a reactor 9, a gas-liquid separator 10, a sample tray 11 of an automatic sampler, a current carrying groove 12 and a sample introduction needle 13. The utility model is characterized in that a current carrying pipe and a sampling valve are removed, a sampling pipe and the current carrying pipe are merged into the sample introduction pipe 1, and samples and carrying current can be made to pass through the same pipe passage. When the interrupted flow device for an atomic fluorophotometer provided by the utility model is adopted, a concentrated reaction is replaced by a fresh reaction for sample liquid surfaces; therefore, the deficiency of the cross contamination of different sample liquid in a pipeline and a liquid leakage phenomenon can be eliminated, the efficiency of hydride generation is enhanced, gas-phase interference is reduced, and precision and detection limits can be improved.
Description
The utility model relates to a kind of sampling device that is used for atomic fluorescence spectrophotometer, particularly a kind of sampling device that is used to have the atomic fluorescence spectrophotometer that hydride takes place that aims at.
At present, the sampling device of atomic fluorescence spectrophotometer has the flow injection instruments sampling device.Because the pipeline of flow injection sampling device between from the sample introduction needle to the sampling valve is special-purpose for sampling, the injection current-carrying is with another pipeline.The shortcoming of this flow injection sampling device is: 1, sampling valve easy-to-leak liquid; 2, different sample liquid produce cross pollution in sample introduction needle and sample introduction pipe.
The purpose of this utility model provide a kind of be used for atomic fluorescence spectrophotometer interrupted flow device, eliminated the defective of different sample liquid cross pollution in pipeline, and eliminated the phenomenon of leakage.
The purpose of this utility model is achieved in that a kind of interrupted flow device that is used for atomic fluorescence spectrophotometer, comprises sample introduction pipe 1, reductive agent pipe 2, sewer pipe 3, sampling ring 4, carrier gas pipe 5, the pipeline 6 that connects atomizer, peristaltic pump 7,8, reactor 9, gas-liquid separator 10, automatic sampler sample disc 11, current-carrying groove 12, sample introduction needle is got, it is characterized in that: remove current-carrying tube and sampling valve, sampling pipe and current-carrying tube are merged into sample introduction pipe 1, can make sample and current-carrying walk same pipeline.
The interrupted flow device that is used for atomic fluorescence spectrophotometer that adopts the utility model to provide has replaced concentrated reaction with fresh sample liquid level reaction, has eliminated the defective and the phenomenon of leakage of different sample liquid cross pollution in pipeline.Improve the efficient that hydride takes place, reduced the gas phase interference, improved precision and detection limit.Simultaneously, the semi-automation of atomic fluorescence spectrophotometer can be realized, the full-automation of atomic fluorescence spectrophotometer can be realized with the interrupted flow device of two peristaltic pumps with the interrupted flow device of single peristaltic pump.The service efficiency and the practicality of atomic fluorescence spectrophotometer have been improved.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the intermittently mobile apparatus structure synoptic diagram of single pump of the present utility model.
Fig. 2 is the intermittently mobile apparatus structure synoptic diagram of double pump of the present utility model.
With reference to Fig. 1, sample introduction pipe 1, reductive agent pipe 2, sewer pipe 3 connects and by peristaltic pump 7 it controlled, sample introduction pipe 1 is by sampling ring 4 coupled reaction devices 9, reactor 9 connects carrier gas pipe 5, reactor 9 is connected to the pipeline 6 that connects atomizer by gas-liquid separator 10, reductive agent pipe 2 is by peristaltic pump 7 coupled reaction devices 9, and sewer pipe 3 connects gas-liquid separator 10 by peristaltic pump 7.
With reference to Fig. 2, reductive agent pipe 2 is by peristaltic pump 8 coupled reaction devices 9, and the sample introduction needle 13 on the sample introduction pipe 1 can be sampled in automatic sampler sample disc 11, draws current-carrying in current-carrying groove 12.
With reference to Fig. 1, Fig. 2, each surveying work process of interrupted flow device can be divided into for three steps.The first step, manual or automatic sampler is placed on sampling needle in the testing sample solution, and testing sample solution enters sampling ring with the certain hour sampling and stores by sample introduction pipe, peristaltic pump.In the reductive agent pipe, the reductive agent solution of potassium borohydride enters reactor with the same time.In second step, the peristaltic pump stall, sample introduction needle and sample introduction pipe are moved in the current-carrying groove.In the 3rd step, peristaltic pump restarts, sampling needle and sampling pipe are drawn current-carrying, sample solution in the promotion sampling ring and the reductive agent in the reductive agent pipe enter reactor, gas-liquid separator, in this step, volatile hydride and excess hydrogen form, and are carried in the quartzy stove by the argon gas that is added in before the reactor, carry out atomization, signal is recorded.By three above-mentioned steps, a complete surveying work process in the interrupted flow device finishes, and the surveying work process of the next sample of interrupted flow device repeats three above-mentioned course of work steps.Because sample solution promoted by current-carrying, current-carrying cleans by preceding whole pipeline by back and another sample solution a sample solution, has eliminated last sample solution residual in the pipeline, has avoided the cross pollution between different sample solutions.
