Learn how you can adopt direct mass spectrometry in your routine analysis workflow.  Adaptation of routine procedures and techniques to automated SIFT-MS will be illustrated with case studies applicable to environmental, consumer product and biomedical laboratory testing. In particular, a head-to-head comparison of GC/MS and SIFT-MS for headspace analysis of volatiles in blood plasma will be described.

This webinar demonstrates the advantages of applying automated SIFT-MS to volatile compound analysis in diverse matrices: from air to the headspace of polymer, soil or water samples. SIFT-MS is not simply advantageous for throughput reasons; it can also support faster method optimization for conventional methods. We include example data and case studies from a range of application areas ranging from pharmaceutical to environmental analysis.

SIFT-MS is a robust analytical technique that addresses the limitations of GC/MS (the incumbent technique). It quantifies VOCs and SVOCs in real-time, with low part-per-trillion detection limits (by volume; pptv), and very wide linear and dynamic ranges.  This brochure outlines the benefits that Syft Technologies’ instruments can provide to researchers in a wide range of disciplines.

In this Syft Tech Talk, Dr. Vaughan Langford introduces the ion-molecule chemistry utilized in SIFT-MS instrumentation. This highly controlled, ultra-soft chemical ionization approach enables SIFT-MS instruments to comprehensively analyze samples with high specificity in real-time.

Syft Technologies’ SIFT-MS instruments quantify volatile compounds in air or headspace in real time… but how do they do it?  Vaughan Langford describes how quantitation direct from the SIFT-MS compound library is performed in Syft Technologies' instruments.

In this webinar, we cover:

• The chemical ionization used in SIFT-MS, and how it provides both selectivity and detection of chemically diverse compounds (including ammonia, formaldehyde, and hydrogen sulfide)
• SIFT-MS quantitation, which is based on ion-molecule reactions, conferring long-term measurement stability and library-based quantitation

The combination of SIFT-MS and a GERSTEL autosampler provides automated analysis of benzene, toluene, ethylbenzene and the xylenes (BTEX) sampled from ambient air using thermal desorption tubes. This application note demonstrates the repeatability and sensitivity possible with automated thermal desorption (TD)-SIFT-MS. Automated TD-SIFT-MS provides sample throughput >3 three-fold higher than conventional TD-gas chromatography methods.

This webinar introduces SIFT-MS and explains the rationale behind seamlessly integrating thermal desorption (TD) with SIFT-MS.  In short, the benefits of coupling TD and SIFT-MS are economic distributed sampling (such as for US EPA Method 325) and much higher throughput for an industry-standard sampling media.

Using the environmentally significant BTEX compounds (benzene, toluene, ethylbenzene and the xylenes) as a case study, we demonstrate high-throughput analysis from several matrices (air, water and soil). For the BTEX compounds, detection limits in the single-digit part-per-billion concentration range (by volume). We also present a calibration approach that enables speciation of ethylbenzene from the xylenes in real-time.

This application note demonstrates the linearity and repeatability achievable for low molecular weight alcohols using automated selected ion flow tube mass spectrometry (SIFT-MS).

SIFT-MS provides direct, rapid sample analysis of volatile organic compounds (VOCs) with no or minimal sample prep required. When coupled with autosampler technology, SIFT-MS yields very high sample throughput (in excess of 100 samples per hour), including for challenging compounds like ammonia, formaldehyde and hydrogen sulfide.  Learn how this direct mass spec technology serves a range of industries, from environmental analysis to food testing to pharma.

In this application note, we demonstrate a fully automated SIFT-MS system coupled to GERSTEL’s MultiPurpose Sampler, with a range of initial applications showing the utility of this automated approach.
