Abstract
A new data processing technique for gas chromatographic-mass spectral data is described. The technique is termed 'Selected Ion Summation Analysis' and is defined as an ion intensity profile generated at the termination of repetitive scanning GC/MS analysis by summing the intensities of selected masses and reporting the summation vs. spectrum number if and only if all masses are present.
