摘要

PROBLEM TO BE SOLVED: To reduce the size of data sets without losing valuable information in processing on mass spectrometric analysis data.;SOLUTION: The method of processing Fourier transformation mass spectrometric analysis data includes the steps of: performing a Fourier transformation on part of time domain transition; and identifying a signal peak indicative of presence of an ion from the transformed data. Once the peak is identified, the whole transition is transformed and the peak identified in a partial transition transformation is used to find a real peak of the transformed whole transition. It is evident that the number of "false" peaks generated from random noise correlates with resolution, so the partial transition is used to identify the real peak. The different parts of all data sets may be transformed and then correlated. Since any noise is random, false peaks are generated at different positions in two partial transformations.;COPYRIGHT: (C)2012,JPO&INPIT
