The results of an investigation of the parameters which have the most significant effect on the accuracy of mass measurements on a quadrupole orthogonal acceleration time-of-flight mass spectrometer(More)
Many formulated products contain complex polymeric excipients such as polyethylene glycols (PEGs). Such excipients can be readily ionized by electrospray and may be present at very high(More)
This work describes the development of a liquid chromatography tandem mass spectrometry (LC-MS/MS) assay for a highly toxic impurity, FMTP (4-(4-fluorophenyl)-1-methyl-1,2,3,6-tetrahydropyridine), in(More)
Gas-phase ion mobility studies of mixtures containing polyethylene glycols (PEG) and an active pharmaceutical ingredient (API), lamivudine, have been carried out using electrospray ionization-ion(More)
For the determination of trace level impurities, analytical chemists are confronted with complex mixtures and difficult separations. New technologies such as high-field asymmetric waveform ion(More)
