Many applications require screening of 100 – 1000 compounds in one MRM method !• Food, environmental and Forensic analysis (e.g. Doping Control)• Subsequent quantitation of positives in dedicated methods
WITHOUT Dynamic MRM• Need to manually set up multiple time segments to maximize dwell time• Tedious and fragile for chromatographic time shifts• Tedious and fragile for chromatographic time shifts
WITH Dynamic MRM• Automatic setup of overlapping time segments without user intervention• Automatic setup of overlapping time segments without user intervention• Even less MRMs per time results in even longer dwell time / sensitivity• Unaffected by chromatographic time shifts
