Abstract

The invention provides a mass spectrum feeding device and mass spectrum detection equipment with the mass spectrum feeding device. The device comprises a spraying device, a sealed cavity, a carrier gas pipeline, a transmission pipeline and an inductive coupling plasma source, wherein the spraying device comprises a feeding pipe, an auxiliary gas pathway and a nozzle, and the nozzle is formed in the sealed cavity; a carrier gas input opening connected with the carrier gas pipeline, an organic mass spectrum sampling interface and an inorganic mass spectrum sampling interface are formed in the sealed cavity; a to-be-detected liquid sample is atomized and ionized under the action of an electric field and an auxiliary airflow, the generated ions are analyzed and detected in a mass spectrometer through the organic mass spectrum sampling interface, and carrier gas input from the carrier gas input opening is used for sending out the sample remained in the sealed cavity through the inorganic mass spectrum sampling interface; and the sample is brought to the inductive coupling plasma source through the transmission pipeline, is atomized and ionized, and is subjected to element composition analysis through a mass spectrometer or a spectrometer. The feeding device can be used for detecting inorganic mass spectrum and organic mass spectrum in parallel.

Description

technical field [0001] The invention relates to a mass spectrometry sampling device and mass spectrometry detection equipment. Background technique [0002] Inductively coupled plasma mass spectrometry (ICP-MS) is recognized as the most powerful elemental analysis technique. Electrospray mass spectrometry (ESI-MS), as the most widely used organic mass spectrometry, can provide composition and structural information of organic compounds, and is used for the analysis and detection of biological macromolecules such as proteins and nucleic acids. With the increasing demand for detection, the same sample often needs to be detected by both inorganic mass spectrometer and organic mass spectrometer to obtain more comprehensive sample information. [0003] However, due to the restriction of the sample injection method, it is still difficult to realize the parallel detection of the two mass spectrometers. At present, most ICP-MS still use a solution pneumatic atomization sampling sy...
