Abstract
Fast atom bombardment (FAB) In conjunction with mass spectrometry/mass spectrometry (MS/MS) was applied to the analysis of anionic sufactants for the first time. Pure materials and commercial products were Investigated. Molecular weight distributions of commercial surfactants could be obtained from either the positive or negative FAB spectra. Collisionally activated dissociation (CAD) spectra of selected Ions were used to confirm strutural Identification. Classes successfully characterized Include alkyl and alkylaryl sulfates and sulfonates, alcohol ether sulfates, α-olefln sulfonates, fatty acid salts, sulfosuccinate diesters, and N-acylated amino acids. The FAB MS/MS technique permits the rapid analysis of these Ionic surfactants without any derlvatization or preseparation.
