| Abstract |
A system of computer programs for recognizing inpure or mixed spectra was assembled that provided automatic subtraction of reference mass spectra from a mixed spectrum. The software was 99% successful in recognizing pure spectra for the cases tested. Subtractions were done on mixed spectra in 70% of the cases tested. Spectrum subtraction enhanced the ability of the matching program to match components of a multicomponent mixture correctly, whereas quality factors were a great aid in the evaluation of the overall match validity. |
