SIFT-MS Analysis of Benzene in Sunscreens and VOC Exposure

This application note summarizes the SIFT-MS results obtained in a study of exposure to VOCs from 26 retail sunscreen products – both VOCs intended as ingredients and those present as contaminants. The commercial products varied widely in VOC content and hence user exposure. Several products contained benzene contamination that was readily quantified using dynamic headspace-SIFT-MS analysis.

Odor Analysis at Gelatin Factory Using SIFT-MS

In this application note, the SIFT-MS is evaluated for odor analysis at a gelatin factory, together with benchmarking of the effectiveness of an ultraviolet (UV) photolysis technology used for odor mitigation. SIFT-MS is very effective in both applications.  The high-sensitivity, direct analysis eliminates preconcentration, derivatization, and the need for analysis on multiple chromatographic columns that complicate odor analysis in gas and liquid chromatography methods.

Untargeted Beer Analysis Using SIFT-MS

Automated, direct headspace analysis using selected ion flow tube mass spectrometry (SIFT-MS) provides rapid and economic screening of food products, ingredients, and packaging materials. This application note describes how SIFT-MS coupled with multivariate statistical analysis provides rapid beer analysis via an untargeted “fingerprinting” approach (i.e. utilizing SIFT-MS SCAN mode). Automated headspace-SIFT-MS analysis can classify beer at throughputs of 12 samples per hour, offering great potential for rapid product screening.

Residual Solvent Analysis: Optimization for DMI Solvent

DMI is a very promising non-aqueous solvent because it can be used even without subsequent dilution in water.  Using a subset of residual solvents, this study confirms that moderately polar volatiles yield headspace responses that are independent of the volume of sample used. This means that cost and environmental impact can be reduced. Furthermore, with SIFT-MS this optimization can be carried out very rapidly due to direct sample analysis and high sample throughput.

Analysis of Volatile Residues in Polymers by SIFT-MS

This application note reviews polymer analysis applications of automated headspace-SIFT-MS. Rapid quality assurance/quality control (QA/QC) screening of over 220 samples/day can be conducted using targeted or untargeted analysis, while quantitative volatile impurity analysis is achieved efficiently using multiple headspace extraction (MHE)-SIFT-MS.

Real-Time Roadside SIFT-MS Monitoring: Unreported VOC Emissions from Road Transport

This application note summarizes key SIFT-MS results obtained and conclusions made in a peer reviewed open-access article entitled “Unreported VOC Emissions from Road Transport Including from Electric Vehicles.”  Learn how the Wolfson Atmospheric Chemistry Laboratory at the University of York used SIFT-MS for VOC analysis in its platform to experimentally verify – for the first time – that motor vehicle screen wash is a significant unreported source of VOC emissions (especially for ethanol and methanol).

EtO and Acetaldehyde in Polysorbate 80: Rapid Quantitative Analysis Using SIFT-MS

This study evaluates a headspace-SIFT-MS approach for Polysorbate 80 products from multiple suppliers and evaluates ethylene oxide and acetaldehyde recoveries. Results confirm that the headspace-SIFT-MS procedure reliably quantifies these analytes without requiring purification of Polysorbate 80 for matrix-matching the calibration standard. Hence, headspace-SIFT-MS analysis of ethylene oxide and acetaldehyde can revolutionize existing workflows.

High-Throughput Analysis of Polymers for Benzene and Volatile MOSH and MOAH Residues

This application note describes the utility of SIFT-MS in pre-screening polymer packaging materials for volatile MOSH and MOAH compounds.  Automated SIFT-MS can characterize 12 high-density polyethylene (HDPE) and polypropylene (PP) samples per hour, or 220 / day.  Headspace-SIFT-MS readily analyzes benzene at high sensitivity as part of the same analysis.

Real-Time Monitoring of Volatile Organic Compounds in Ambient Air Using Direct Injection Mass Spectrometry

In this article, the results of a DIMS air monitoring campaign in Auckland, New Zealand, are described. Real-time SIFT–MS measurements were obtained at three sites over a period of several weeks each. At each site, SIFT–MS provided effective on-site analysis to sub-ppbV levels with better than 1-min time resolution.
