This week, Chromatography Online explored how the technique is advancing wastewater drug monitoring, siRNA method development, and food safety testing, with previews of RAFA 2026 and a return to HPLC fundamentals with Michael Dong.
Quantitative analysis of volatile nitrosamine impurities in drug products is greatly simplified using SIFT-MS and has a three-fold throughput advantage (excluding sample prep benefits) over chromatographic methods. This application note describes the headspace-SIFT-MS analysis of ranitidine products which achieves a limit of quantitation of 2 ng g-1 for NDMA in 500 mg of drug product.
