Abstract
Negative ion atmospheric pressure ionization mass spectrometry has been used to investigate the gas phase atmospheric pressure anion chemistry of N 2O 2H − and ▪. N 2O 2H − has been shown to be a stronger base than ▪. Specific types of reaction ( e.g. proton abstraction, and dehydration) have been identified for each of these anions. Although the analytical significance of these reactions has not yet been demonstrated, certain compounds such as alcohols which do not readily attach electrons directly can easily be detected by observing a specific anion reaction product. The technique appears to provide an additional dimension to established gas chromatographic—mass spectrometric analyses.
