| Abstract |
Chemical ionization conditions were developed for obtaining mass spectra that bear a striking resemblance to electron impact (EI) spectra. The method, which employs charge exchange reactions in a high-pressure source, is applied to the identification of priority pollutants. In most cases, identification of the compounds by using computer-generated searches of the pseudo-EI spectra against libraries of true EI spectra was possible with confidence levels of 80% or greater.
