Title:
MASS SPECTROMETRY DEVICE AND MASS SPECTROMETRY METHOD
Document Type and Number:
WIPO Patent Application WO/2023/013161
Kind Code:
A1
Abstract:
This mass spectrometry method comprises: a step 1 for introducing precursor ions into a reaction chamber; steps 7, 8 for generating a radical by generating plasma by transmitting a predetermined control signal to a source gas supply unit and a high-frequency power supply unit to supply source gas and high-frequency power to a radical generation chamber for a predetermined period; a step 17 for generating product ions by introducing the radical into the reaction chamber; a step 10 for measuring the intensity of light in a wavelength band including the wavelength of light emitted from the plasma in the radical generation chamber; and a step 3 for, on the basis of the fact that the intensity of light exceeds a predetermined abnormality determination threshold in a period other than the predetermined period, determines and reports device abnormality.
