摘要: Differences in the designs of two liquid chromatography particle beam mass spectrometry systems result differences transport ammonium acetate and ion abundance-enhancing carrier effects. The effect mobile phase composition, especially proportion water phase, on efficiency is described. Instrument detection limits for 12 compounds with different interface are presented. calibrations generally nonlinear explained terms effects supported by experiments isotopically labeled species that coelute native species. Summary results a small multilaboratory study Calibration isotopitally internal standards recommended real-world environmental samples.
