Title:
LIQUID CHROMATOGRAPH MASS SPECTROMETER
Document Type and Number:
WIPO Patent Application WO/2020/162438
Kind Code:
A1
Abstract:
Provided is a liquid chromatograph mass spectrometer that prevents contamination of a pump or a column and can execute mass calibration without adding a complicated mechanism. This liquid chromatograph mass spectrometer comprises: a liquid chromatograph that includes a liquid delivery pump configured to deliver a mobile phase solvent; a mass spectrometer that analyzes the mass of a sample; and a standard sample container that is configured so as to connect the liquid chromatograph and the mass spectrometer in series to each other in a flow path connecting the liquid chromatograph and the mass spectrometer, and that accommodates a standard sample for the mass calibration.
