LIQUID CHROMATOGRAPH MASS SPECTROMETER

摘要

PROBLEM TO BE SOLVED: To provide a liquid chromatograph mass spectrometer capable of performing a highly accurate measurement by preventing precipitation of non-volatile salt, metallic ions, and a polymer to a tip of a spray nozzle part regardless of presence/absence of a desalination column and a flow path.

SOLUTION: A liquid chromatograph mass spectrometer includes: a spout part 1 for spouting sample solution fed from a liquid chromatograph towards a drain part 4 or a sample introduction part 31 of a mass spectrometer 3; and an articulated robot 2 determining a position of the spout part 1 so as to be changed between a spout position to the drain part 4 and a spout position to the sample introduction part 31.
