Notes:
In this paper we report our studies of reduction phenomena in a high performance liquid chromatography/particle beam interface-mass spectrometer system (HPLC/PB-MS). It is shown that reduction takes place in the ion source of the mass spectrometer, but that the particle beam interface plays an important role in the reduction process since the HPLC mobile phase is involved in the reduction. HPLC flow rate and desolvation-chamber temperature have significant effects on the reduction extent, while ion-source temperature has only a minor effect. All the nitro compounds and sulfoxides tested in this work showed reduction in the system. There was no observed reduction for sulfones. 1,4-Naphthaquinone showed significant reduction, while no reduction was observed for anthraqunone.
