Collision-induced dissociation of ions within the orifice-skimmer region of an electrospray mass spectrometer


An equation was derived to describe the variation of the gas number density within the region between the orifice and the skimmer of an electrospray ionization mass spectrometer. The equation was used to develop a semi-quantitative model to predict the value of orifice voltages that lead to ion fragmentation within this region. This model made it possible… (More)
