Title:
MASS SPECTROMETRY DEVICE WHEREIN ULTRAVIOLET LIGHT IONISES LOST NEUTRAL MOLECULES, AND OPERATING METHOD FOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/041361
Kind Code:
A1
Abstract:
Provided is a mass spectrometry device wherein ultraviolet light ionises lost neutral molecules, and an operating method for the device. The mass spectrometry device wherein ultraviolet light ionises lost neutral molecules comprises essential components of a mass spectrometry device such as a quadrupole series connection special linear ion trap (134) mass analyser, a vacuum ultraviolet lamp (142), a shutter in front of the lamp (141) and a gradient vacuum system (110). Also provided is a method for operating the device to perform high efficiency ion storage, ion fragmentation and ion analysis, high efficiency ionisation of lost neutral molecules by ultraviolet light, and ion re-analysis.
