SIFT-MS has unique advantages in air quality measurement applications. It enables environmental incidents to be detected and remedied before they escalate.

This application note demonstrates that automated headspace-SIFT-MS analysis has the potential to screen larger sample numbers for the volatile MOH fraction, providing a rapid indication of packaging material contamination. As benzene has also recently been found to be problematic in commercial products, Headspace-SIFT-MS can screen over 220 samples per day for volatile MOSH and MOAH compounds – nearly seven-fold more samples than the routine liquid and gas chromatography method.

Quantitative analysis of volatile nitrosamine impurities in drug products is simplified using SIFT-MS and has a 3X throughput advantage over chromatographic methods.

In this study, Syft Tracer analyzed the same samples in 9 hours that took 5 chromatographic systems 24 hours to complete and still had capacity to spare.
