This study describes the use of headspace sorptive extraction with GCxGC-TOF MS to compare the volatile profiles of ground meat and plant-based substitutes.

The accurate identification and measurement of biomarkers in biological samples - such as breath and biofluids - has the potential to provide rapid, minimally-evasive diagnosis of a range of physiological and pathological conditions. In this application guide, SepSolve Analytical describes how flexible sampling coupled with high-performance GC-MS or GCxGC-MS enables the maximum possible number of compounds to be identified in a realistic run time.

In this study, SepSolve Analytical describes the comprehensive, high-sensitivity screening of disease biomarkers, through use of sampling onto TD tubes, automated preconcentration, and GCxGC-TOF MS.

This study by SepSolve Analytical describes the development of an analytical platform based upon TD-GCxGC-TOF MS and shows its application to the collection and analysis of breath samples.

This study demonstrates the performance of flow-modulated GC×GC for robust group-type characterisation of jet fuels, with quantitative analysis by flame ionisation detection (FID) and confident identification of trace-level contaminants by mass spectrometry.

Comprehensive two-dimensional gas chromatography (GC×GC) is an advanced analytical technique with an increased separation capacity suitable for the analysis of complex samples. This application note demonstrates some of the most important applications of two-dimensional gas chromatography.

This scientific poster evaluates differences in terpene composition for the same cannabis strain grown under different conditions.

Analysis by comprehensive two-dimensional gas chromatography coupled with time-of-flight mass spectrometry (GC×GC–TOF MS) provides the enhanced separation necessary to resolve complex mixtures. This scientific poster demonstrates the enhanced performance of a multi-functional TD–GC×GC–TOF MS system by simulating disease biomarkers through a controlled, artificial change in participants’ breath.

Volatile profiling of food and beverages is crucial for understanding and enhancing their quality, safety, and consumer appeal. Analysing these volatiles presents several challenges due to the diversity of chemical classes, their varying concentrations, and the complex matrices involved, which can be problematic for conventional gas chromatography–mass spectrometry (GC–MS) approaches.

Join Prof. Kieran Kilcawley, Principal Research Officer at Teagasc Food Research Centre and Adjunct Professor, University College Cork and Technological University Dublin, as he explores how innovative extraction and enrichment techniques, combined with state-of-the-art GC–MS analyses, can overcome these difficulties and deliver more detailed and accurate volatile profiles.

Liquid smoke is the name given to flavoring products that claim to enhance food by adding a ‘smoked’ flavor to mimic the traditional smoking process.

Due to the complex nature of liquid smoke, the European Food Safety Authority (EFSA) issued new guidelines in February 2021 for the analysis of such products prior to authorization. The new guidelines call for full chemical characterization of the primary product, meaning that non-target analysis is required.

In this SelectScience webinar, discover how GC×GC–TOF MS coupled with innovative chemometrics software can provide comprehensive comparison of liquid smoke composition to improve quality control procedures and to accelerate the development of new flavorings.

Key learning objectives

• How GC×GC–BenchTOF2 can gain greater insights into sample composition for robust aroma and flavor profiling
• How Tandem Ionization® can be used to improve confidence in compound identification and enhance non-target workflows
• How smart software workflows can automatically uncover key differences between complex flavor profiles

Who should attend?

• GC(-MS) users who want to enhance their ability to analyze complex samples
• Food, fragrance and flavor scientists interested in how advanced analytical techniques can provide a competitive edge

With the increased uptake of hybrid and electric vehicles, non-exhaust emissions are now of growing environmental concern. In this webinar, our guest speaker, Dr Nick Molden, (Emissions Analytics), will demonstrate the use of thermal desorption (TD) for versatile sampling of emissions from exhausts, vehicle interiors and tyres. When coupled with GC×GC–TOF MS this provides improved chemical fingerprinting of emissions to enhance our understanding of how vehicles may impact the environment and human health.

Key learning objectives

• See how GC×GC–TOF MS can gain insight into volatile emissions from car trim materials, such as plastic, textiles and rubber.
• Find out how characterising tyre composition can help us to understand the sources of microplastics being observed in air, water and soil samples.
• Learn how to future-proof your lab in case of expansion of the target lists of regulated compounds.

Who should attend?

• GC-MS analysts, lab supervisors and directors
