Problems solved by technology

Sampling devices are required in the process of testing samples. At present, when sampling devices of mass spectrometers are used to sample different samples, the sample reagents are prone to internal liquid accumulation and confusion during transmission and detection, resulting in their overall separation during component testing. The operation is relatively cumbersome and complicated, and, affected by the characteristics of the reagents before detection, some reagents to be tested are prone to long-term retention losses of ions, resulting in partial leakage in the detection. Therefore, it is necessary to propose a mass spectrometer sampling device to solve the above problems

Abstract

The invention discloses a sampling device for a mass spectrometer, which includes a carrying table, a sample storage box, an auxiliary static device, a detection platform and a sampling body assembly. device; the auxiliary static device carries out internal local pressurization and static for the test sample in the test piece before the test sample enters the extraction and sampling process, so that the samples in the test sample can enter the analysis device in sequence The other side of the upper end surface of the bearing workbench is equipped with a sampling body assembly, and the sampling body assembly sequentially samples the test samples of each bearing test piece from top to bottom; the upper end surface of the bearing workbench is located at A detection platform is arranged on the same side of the sampling body assembly, and the detection platform transports the sample to the detection platform for analysis and detection after the sampling body assembly completes the sampling work.

Description

technical field [0001] The invention relates to the technical field of mass spectrometer test equipment, in particular to a mass spectrometer sampling device. Background technique [0002] A mass spectrometer is a common experimental instrument, also known as a mass spectrometer. An instrument for separating and detecting different isotopes. That is, according to the principle that charged particles can be deflected in an electromagnetic field, a type of instrument is used to separate and detect material composition according to the mass difference of material atoms, molecules or molecular fragments. Sampling devices are required in the process of testing samples. At present, when sampling devices of mass spectrometers are used to sample different samples, the sample reagents are prone to internal liquid accumulation and confusion during transmission and detection, resulting in their overall separation during component testing. The operation is relatively cumbersome and co...
