Application Notes: General
Analysis of N-Nitrosodimethylamine (NDMA) Impurity in Rantidine Products Using SIFT-MS
February 21st 2024Quantitative 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.
Real-Time Monitoring of Bioreactor Production Processes Using SIFT-MS
February 21st 2024The ability of SIFT-MS to monitor critical volatile organic compounds (VOCs) produced by a bioreactor in real-time at low parts-per-billion by volume (ppbV) concentrations is demonstrated. This application note presents the results of a pilot-scale feasibility study conducted over several weeks, demonstrating the utility of SIFT-MS for maximizing production outcomes.
