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.
High-Throughput Screening of Polypropylene Polymer using Untargeted Headspace-SIFT-MS Analysis
This application note describes how SIFT-MS coupled with multivariate statistical analysis can be utilized for rapid screening of pelleted virgin and recycled polypropylene using an untargeted “fingerprinting” approach. Automated headspace-SIFT-MS analysis can classify and qualify polypropylene samples at throughputs of over 230 samples per day, offering great potential for rapid screening of recycled polypropylene feedstock for FCM applications. Adoption of SIFT-MS supports product quality and enhances sustainability.
Real-Time Analysis of Volatile Emissions from Hot-Melt Extrusion using Untargeted SIFT-MS
SIFT-MS provides unique capabilities that enable formulators to optimize the hot melt extrusion processes by minimizing polymer, API, and other excipient degradation. SIFT-MS provides real-time feedback though online, ultra-trace, gas-phase analysis of the small molecules emitted when the mixture is extruded, benefiting process development and optimization, as well as continuous process monitoring and control.
Improved MHE-SIFT-MS Workflows - Concentration Independent MHE Calibration
This application note investigates concentration dependence of MHE calibration in sample matrix. Across the full range of analytes investigated in this study, MHE calibration holds for at least one order of magnitude change in sample concentration. For analytes in the C7–C9 range, the MHE calibration applies over two orders of magnitude analyte concentration. These results mean that the MHE workflow can be applied to a wider range of samples in the matrix, further reducing calibration demand.

Pharmaceutical Residual Solvent Analysis: A Comparison of GC-FID and SIFT-MS Performance
This study expands upon the previous work by conducting a head-to-head comparison of GC-flame ionization detection (GC-FID) and SIFT-MS procedures. SIFT-MS analyzed samples over 11-fold faster than GC-FID, increasing daily sample throughput and reducing the time taken to determine the result. The results suggests that residual solvent analysis using SIFT-MS may support workflow improvements for pharmaceutical manufacturers.

Extending SIFT-MS Residual Solvent and Volatile Impurity Analysis to Water-Insoluble Articles
SIFT-MS can analyze residual solvents and other volatile impurities in water-insoluble articles using a two-step process: dissolution in compatible solvent, then dilution in water. This application note describes a systematic evaluation of the compatibility of six organic solvents with headspace-SIFT-MS analysis following this two-step process. Quantitative headspace analysis is achieved at 12 samples/hr, providing significant productivity improvements compared with chromatographic approaches.

The characteristic flexibility, stability, high throughput, and fast time to data of the Syft Tracer next-gen SIFT-MS instrument apply across multiple headspace approaches for diverse matrices. This application note briefly summarizes the use of (1) dissolution, (2) multiple headspace extraction (MHE), and (3) the method of standard additions, then provides a guide for identifying the appropriate headspace approach for various matrices.
Wastewater Odor Analysis by SIFT-MS
In this application note, the performance of SIFT-MS is evaluated for analysis of odors from diverse sources at a modern wastewater treatment plant (WWTP). SIFT-MS provides comprehensive, quantitative profiling of odor sources and can identify operational abnormalities. In particular, the results presented demonstrate that methyl mercaptan is almost always a more significant odorant at this WWTP than hydrogen sulfide and confirm that the relative abundances of these odorants vary significantly.
