SIFT-MS has been widely applied to quantitative analysis of a broad range of VOCs in applications from food products to workplace safety to environmental monitoring, and most recently to pharmaceutical testing. This review surveys the applications of SIFT-MS in odor analysis and in workplace, environmental and consumer protection, with a particular focus on the complementarity of this real-time mass spectrometry analyzer to sensor technology and conventional laboratory techniques—in particular, gas chromatography–mass spectrometry (GC/MS).

SIFT‐MS is now recognized as the most versatile analytical technique for the identification and quantification of trace gases down to the parts‐per‐trillion by volume, pptv, range. This statement is supported by the wide reach of its applications, from real‐time analysis, obviating sample collection of very humid exhaled breath, to its adoption in industrial scenarios for air quality monitoring. This review touches on the recent extensions to the underpinning ion chemistry kinetics library and the alternative challenge of using nitrogen carrier gas instead of helium. 

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 app note introduces the next generation of SIFT-MS, Syft Tracer^TM, which launched at Pittcon 2023.  It revolutionizes volatile impurities analysis workflows through unparalleled speed, performance stability, and reproducibility.  Learn about how this innovation to real-time trace gas detection outpaces chromatography-based methods in the analysis of challenging analytes such as formaldehyde in a PEG excipient.

MHE-SIFT-MS provides rapid, matrix-independent, quantitative determination of volatile leachables in polymers and calibrates quantitative analysis based on single headspace injections.  This approach enables over 200 samples per day to be analyzed, delivering rapid and economic analysis of volatile leachables such as residual monomers.

Pharmaceutical and food products are susceptible to contamination from packaging, whether from polymeric materials, printing inks, or paperboard.  SIFT-MS, a high-sensitivity direct-injection mass spectrometry technique, enables risks associated with sustainable packaging alternatives to be mitigated through economical, high-throughput automated analysis (typically a 4- to 15-fold increase over GC-MS).

Selected ion flow tube mass spectrometry (SIFT-MS) is a revolutionary direct mass spectrometric technology for continuous, sensitive, selective, and robust analysis of diverse chemical species in air. Volatile organic compounds (VOCs) — such as benzene, ammonia, and formaldehyde — and inorganic gases such as sulfur dioxide and hydrogen sulfide are detected simultaneously and continuously in real time.  Watch the webinar to discover why SIFT-MS is well suited to air quality monitoring both in a mobile deployment scenario and for fence line monitoring.

SIFT-MS provides real-time, selective, and economic analysis of challenging volatile compounds, such as residual solvents, formaldehyde, dimethylamine, and NDMA without requiring derivatization or other special handling.

Automated SIFT-MS analysis coupled with multivariate statistical analysis provides rapid sensory screening of paperboard packaging, overcoming the low sample throughput of sensory panels.  The ability to use HS-SIFT-MS to achieve throughput of 12 samples per hour is demonstrated.

Quantitative determination of volatile aldehyde residues in paperboard is readily achieved using multiple headspace extraction-SIFT-MS analysis, with an eight-fold throughput increase over the equivalent conventional analysis.

Automated SIFT-MS analysis rapidly screens paperboard packaging for a wide range of functional groups in a single analysis, assuring that the volatile emissions meet manufacturer specifications.  This application note describes a Headspace-SIFT-MS method with throughput >10X faster than traditional GC/MS methods.
