Hear About the Latest Advancement to the SIFT-MS Platform
SIFT-MS is a direct-injection mass spectrometry technique that provides real-time, selective, and economic analysis of volatile compounds in the gas phase. Syft TracerTM is the next generation of real-time, direct injection mass spectrometry (MS) which is launching at Pittcon 2023. It provides the newest, most sensitive, and most robust platform of SIFT-MS technology.
Read MoreMHE-SIFT-MS Provides 8X Faster Quantitative Analysis of VOCs in Packaging and Polymers
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.
Read MoreSIFT-MS Quantifies the Widest Range of Odor Compounds in a Single Analysis with High Throughput
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.
Read MoreMHE-SIFT-MS Provides 8X Throughput Advantage Over MHE-GC for Screening for Aldehydes in Paperboard
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.
Read MoreStatic Headspace-SIFT-MS Method for Screening Paperboard Leachables is >10x Faster than GC-MS
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.

We asked David Light, CEO and Founder of Valisure, to tell us about his experience using SIFT-MS. He describes how Syft technology enables his organization to investigate real-use scenarios because of its real-time data collection capabilities.
Read MoreRapid Screening of Recycled Packaging Materials by SIFT-MS
Automated headspace-SIFT-MS analysis can classify HDPE at throughputs over 230 samples per day, offering great potential for rapid screening of recycled packaging materials.
Read MoreReal-Time Monitoring of Bioreactor Fermentation Compounds Using SIFT-MS
The 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.
Read MoreSIFT-MS provides rapid analysis of benzene in consumer products
SIFT-MS provides rapid, sensitive, and robust analysis of benzene and other contaminants in a wide array of commercial products. Integration with a headspace autosampler enables rapid screening of hundreds of samples per day. In this study, four commercial personal care product matrices were tested: a crushed tablet, a syrup, a creamy lotion (called ‘lotion’) and an oily lotion.
Read MoreA Sensory Expert Shares His Experience Using SIFT-MS
We asked Mike McGinley, President, St. Croix Sensory, Inc. about his experience using SIFT-MS.
Read MoreHeadspace-SIFT-MS is 7X Faster Than LC and GC Analysis of MOSH and MOAH Compounds
Comprehensive analysis of Mineral oil hydrocarbons (MOH) is very challenging and time consuming. Headspace-SIFT-MS can screen over 220 samples per day for the volatile fraction – nearly seven-fold more samples than the routine liquid and gas chromatography method.
