Abstract
A method for checking a validity of a mass axis calibration of a mass spectrometer (MS) of an analyzer system, comprising obtaining a mass axis check sample spanning a predetermined m/z measurement range of the MS and automatically processing the sample, performing multiple full scan mode MS measurements of different types using the MS for the at least two mass axis points to obtain measurement data, wherein the different types include at least a first full scan MS measurement in a positive mode and a second measurement in a negative mode, or at least a first full scan measurement for a first mass filter and a second full scan measurement for a second mass filter; comparing the measurement data for each of the at least two mass axis points with respective reference data and determining if a condition is out of specification based on a result of the comparing steps.
