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