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.

In this webinar, we demonstrate the advantages of using automated SIFT-MS to analyze volatiles in diverse matrices: from air samples to the headspace of polymers, soil and water samples. Formaldehyde and the BTEX compounds (benzene, toluene, ethylbenzene and the xylenes) will be utilized in various case studies. In addition, high-throughput thermal desorption-SIFT-MS and real-time thermal extraction-SIFT-MS are presented for the first time.

The power of SIFT-MS for measuring volatiles can be harnessed in a number of different ways in the food industry. For example, SIFT-MS has applications in consumer perception of food flavor, determining causes of food spoilage, detecting food adulteration and identifying the origin of food products. Using case studies on the analysis of fruit juice, cheese, honey and garlic, Professor Barringer discusses these applications.

Volatile organic compounds (VOCs) form a key component in the expression of sensory and characteristics for confectionery products. This white paper describes the VOC analysis capabilities of Selected Ion Flow Tube Mass Spectrometry (SIFT-MS) that are relevant to flavour-release research and manufacturing of confectionery. The application of these capabilities is illustrated, with results from actual analyses presented.

SIFT-MS provides unique solutions to difficult analytical challenges faced within the food, flavors, and fragrances industry.  This direct mass spectrometry technique offers unmatched speed, sensitivity, and selectivity that are paired with a wide dynamic range for detecting VOCs.  This
brochure outlines several SIFT-MS based food, flavor and fragrance solutions that Syft provides.

SIFT-MS is a revolutionary direct analysis technology for fast, sensitive, selective and robust analysis of flavor compounds in air or headspace at trace levels. 

In this webinar, we introduce the SIFT-MS technique and a variety of food and flavor applications, including:

• Headspace and in vivo flavor analysis

• Process monitoring

• Sensory screening

• Packaging testing

In this webinar, we describe the benefits of SIFT-MS for flavor analysis using various application examples:

• Flavor development during processing of tomato, mango and cocoa
• Enzymatic flavor generation in fresh tomatoes and strawberries
• In vivo assessment of “garlic breath” deodorization
