Abstract
A sample may be analyzed by sampling a quantity of the sample so as to provide a respective quantity of vapor phase molecules of the respective complex sample to a, mass sensor; performing a succession of scans of the sample, so as to generate a respective series of mass spectra; compiling a k×n vector matrix representative of a plurality of temporal profiles derived from the plurality of mass spectra; performing one or more multivariate data analysis routines with respect to the vector matrix; and, in response to the multivariate data analysis routine, reporting the results of the analysis.
Claims3
The method comprising the steps of:
- providing a sample not in equilibria to a mass sensor as the sample is changing state;
- performing a succession of scans to generate mass spectra of volatile vapor phase constituents generated as the sample is changing state over time;
- obtaining a temporal profile of charged constituents formed as a result of the succession of the scans that generated the mass spectra, the temporal profile being at least partially representative of the mass sensor response to the sample;
- performing a multivariate data analysis routine with respect to the temporal profile;
- and
- supplying results of the multivariate data analysis routine.
