Title:
MASS SPECTROMETRY DEVICE AND ION DETECTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/126067
Kind Code:
A1
Abstract:
The objective of the invention is to provide a mass spectrometry device and an ion detection method therefor such that an ion amount can be detected with high accuracy.
In order to achieve the above-mentioned objective, the mass spectrometry device (100) performs a channel scan measurement by varying the voltage applied to a mass separation unit (102) and selectively extracting a desired ion. The mass spectrometry device comprises: an ion detection unit (103) for detecting the ion separated by the mass separation unit (102) and outputting an electrical signal; an ion amount measurement unit (104) for measuring an ion amount from the output of the ion detection unit (103); and an ion amount correction unit (105) for correcting the ion detection amount from the output of the ion amount measurement unit (104). The ion amount correction unit (105) is configured in such a manner that the ion detection amount detected in the current channel is corrected on the basis of the ion detection amount from one channel prior in the channel scan process.
