Abstract
A plurality of product ion spectra measured over plurality of cycles for each precursor ion mass selection window of two or more precursor ion mass selection windows are received from a tandem mass spectrometer. A product ion extracted ion chroatograms (XIC) is calculated for each precursor ion mass selection window of the two or more precursor ion mass selection windows from the plurality of product ion spectra for each precursor ion mass selection window. Two or more product ion XICs are produced. A two-dimensional binary bit matrix is generated to represent each product ion XIC of the two or more product ion XICs. For each XIC of the two or more product ion XICs, the binary bit matrix is separately initialized with binary values calculated from each XIC and the initialized binary bit matrix is compared with stored information about known compounds to identify known compounds of each XIC.
