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.
This application note describes head-to-head comparison of GC-FID and SIFT-MS analyses of Class 2A and 2B residual solvents. The techniques perform similarly for linearity and repeatability, but SIFT-MS provides superior performance for accuracy and recovery. Furthermore, SIFT-MS provides greater than 11-fold increase in sample throughput and significantly reduces the time taken to report quantitative results (over six times faster for a full calibration set).
This application note describes how SIFT-MS greatly simplifies formaldehyde detection and quantitation through direct, instantaneous, and sensitive (sub-ppbV) sample ionization. Sample throughputs of up to 250+ samples/day are possible using the method detailed in this study.
