Fundamentals and Applications of Atmospheric Pressure Chemical Ionization Quadrupole Ion Trap Mass Spectrometry for the Analysis of Explosives
Abstract
The goal of this research was to develop a liquid chromatography (LC)/atmospheric pressure chemical ionization (APCI)-mass spectrometry (MS) and tandem mass spectrometry (MS/MS) method for the analysis of explosives. APCI and electrospray ionization (ESI) are soft ionization techniques which produce characteristic ions of explosives at atmospheric pressure. Most explosives are susceptible to impurities in the solvent and form adduct ions instead of molecular-type ions. Additives allow specific adduct ions to be preferentially formed, which increases the sensitivity for explosives and improves spectral consistency. However, these adduct ions are formed by weak van der Waals forces that can be easily dissociated by the energy imparted during vaporization.
