MASS SPECTROSCOPE AND MASS SPECTROMETRY

摘要

PROBLEM TO BE SOLVED: To stably measure a hydride generating element with high sensitivity wherein, with an element contained in a measurement sample is combined with hydrogen to generate a gaseous hydride, the gaseous hydride is guided into a plasma ion source mass spectrometer for measuring the hydride generating element. SOLUTION: A hydride generating device is connected to the plasma ion source mass spectrometer to measure a hydride generating element. Here, the flow rate of gas guided into the plasma ion mass spectrometer from the hydride generating device is adjusted.
