Abstract
Method and systems for monitoring ion mobility spectrometers are provided. The method can include acquiring scan data, and generating a segment data set from the scan data. The method can further include deriving a subset of peak data from the segment data, where the subset of peak data has an associated set of peak metrics, and deriving a value from the subset of peak data associated with a criteria element of the associated set of peak metrics, where the criteria element has an associated range of values. The method can further include providing an indication in the event the value lies outside the associated range of values.
