ピーク形状やマスディフェクト値に注目してマススペクトルにおけるFalse Positiveデータを見極める

In recent years, mass spectrometer (MS) has become more sophisticated and black-boxed, making it possible for anyone to acquire data with simple operations. However, it is undeniable that even in mass spectra obtained by high-performance MS, there is a possibility that non-significant signals, so-called "false positive" data, are mixed in. I would like to introduce a method to identify false positive data by carefully viewing mass spectra with attention to the peak shapes of ion profiles and mass defect values.
