For two-component mixtures, Kebarle and Tang observed that the ionization efficiency (i.e., yield of ions per unit concentration) depends strongly on the concentration and nature of other ionizable species and weakly on total concentration of ionized species. In this work, the model used by Kebarle
Ammonia desorption chemical ionization mass spectra (NH3-DCIMS) of phosphatidylsulfocholines, a mixture of a homologous series of phosphatidylsulfocholines (PSC) and a mixture of a PSC and a phosphatidylcholine (PC), were measured by a flash heating method involving introduction of 1/xg of the sampl
