The applicability of thermal surface ionization in liquid chromatography/particle-beam mass spectrometry is investigated for the analysis of quaternary ammonium compounds. The compounds are mass anlyzed in a filament-off mode of operation with a particle-beam interface. An intense signal of the molecular cations is observed, while fragmentation can be induced by gas collisions and characterized using tandem mass spectrometry. A significant gain in signal-to-noise ratio in thermal surface ionization relative to electron ionization is observed.
