ABSTRACT:
A mass spectrometry system is described. The mass spectrometry system includes an ion source to ionize a sample stream, a detector positioned downstream with respect to the ion source to acquire mass spectrometry data of the sample stream, and a data analyzer connected to the detector. The data analyzer includes a chromatogram generator to process the mass spectrometry data to derive a chromatogram, a data point selector to apply a selection criterion to the chromatogram to select data points from the chromatogram, and a peak discriminator to apply a discriminating criterion to the data points to detect a peak in the chromatogram, wherein the peak is indicative of a presence of an analyte in the sample stream. A computer-readable medium for a mass spectrometry system and a method of processing mass spectrometry data are also described.
