Title:
MASS ANALYSIS SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2014/041886
Kind Code:
A1
Abstract:
This mass analysis system has: a mass analysis unit (110) for measuring a sample and outputting a mass spectrum; a space charge effect correction unit (202) for correcting for the space charge effect on the basis of the mass spectrum and outputting same as a corrected spectrum; and a correction reliability calculation unit (203) for calculating the reliability when a correction has been made on the basis of the mass spectrum. According to the present invention, the reliability of the effect of correcting for the space charge effect can be accurately assessed.
