Abstract

Negative ion chemical ionization (NCI) mass spectrometry using isobutane as a reagent has been applied to the analysis of explosives. The method is evaluated as complementary to positive ion CI, as both methods can be applied to the same sample. We used a magneticsector-type mass spectrometer without changing the electron multiplier voltage. Under these conditions NCI mass spectra of explosives have been obtained at a sensitivity similar to that of positive ion CI mass spectra.
