Ultrahigh-performance liquid chromatography–tandem mass spectrometry (UHPLC–MS/MS) shows flonicamid residues in rice pose negligible dietary risk.
Quantitative ethylene oxide analysis in Polysorbate 80 excipient is greatly simplified using SIFT-MS, with a time to first test result that is eight-fold faster than the current compendial method and a daily sample throughput that is 9- to 14-fold higher. In this application note, a simplified EtO method is presented that uses a much smaller quantity of PS80 for analysis than headspace GC-FID.
