Abstract (en)

[origin: WO2011058381A1] The invention relates to a method of screening and/or detecting and/or quantifying the amount of one or more compounds of interest in a sample. The invention also relates to a control system and mass spectrometer programmed to carry out the method. The method involves identifying one or more parent and/or daughter ion masses of interest, acquiring a first data set from the sample, determining the presence of candidate parent ions of interest and/or a first set of candidate daughter ions of interest in the first data set, selecting the candidate parent ions of interest, fragmenting the selected candidate parent ions of interest to produce a second set of candidate daughter ions of interest and creating a mass spectrum of at least some of the second set of candidate daughter ions of interest. One embodiment of the invention involves determining or calculating the quantity of at least a first compound of interest from the mass spectrum. Another embodiment of the invention involves confirming the presence or absence of a first compound of interest in the mass spectrum.
