ABSTRACT:
Screening an unknown sample for a plurality of known or "target" analytes may be accomplished by creating and searching a retention time-locked spectral database for the entire chromatographic output of a locked GC system locked to such spectral database. Identification of target analytes having for example, known significant mass spectral ions and mass ion ratios corresponding to known analytes of interest believed to be found within a pre-defined retention time window is improved by direct comparison of significant mass spectral ions and the mass ion ratios within a specified retention time window.
