| 发明名称 | Method of processing image charge/current signals | ||
| 摘要 | A method of processing an image charge/current signal representative of trapped ions undergoing oscillatory motion. The method includes applying a validity test to each of a plurality of peaks in the image charge/current signal in the frequency domain, wherein applying the validity test to a peak in the image charge/current signal in the frequency domain includes determining whether a phase angle associated with the peak meets a predetermined condition. The method also includes forming a new image charge/current signal that: includes data representative of one or more peaks that have passed the validity test; and excludes data representative of one or more peaks that have failed the validity test. The method may be performed by a mass spectrometry apparatus. | ||
