Transfer of Existing Forensic LC/MS and LC/MS/MS Mass Spectral Libraries to Linear Ion Trap Instrumentation

Mass spectral libraries are necessary for the General Unknown Screening in e.g. forensic or environmental analysis. Several libraries were developed and successfully applied by different working groups. The transfer of existing libraries to quadrupole instruments of same and another manufacturer was already investigated. The following poster describes the possibility of transferring existing mass spectral libraries set-up on a triple quadrupole instrument in Q1 scan with in-source fragmentation and product ion scan to a linear ion trap mass spectrometer. Test compounds were used for the adjustment of critical voltages responsible for the fragmentation in different MS and MS/MS modes. High sensitivity in scanning modes of the used linear ion trap allows screening for unknown forensic relevant compounds in real samples
