Improved characterisation of malodours from recycled plastics using TD–GCxGC–TOF

This poster, presented at Pittcon 2023, illustrates how thermal desorption (TD) coupled TD–GCxGC–TOF MS can address the challenges of odour profiling of recycled plastics, by providing high sensitivity and improved separation prior to confident identification of the individual analytes.

Using GC×GC–TOF MS to compare VOC profiles of food and beverages

Using high-capacity sorptive extraction with novel trap-based focusing to provide enhanced sensitivity and improved chromatographic performance. This improved performance, coupled with enhanced separation by GC×GC and highly-sensitive detection by time-of-flight mass spectrometry (TOF MS), gains greater insight into sample composition.

Monitoring disinfection by-products in water using thin-film SPME with GC×GC–TOF

This poster demonstrates how thin-film solid-phase microextraction (TF-SPME) with comprehensive two-dimensional gas chromatography and BenchTOF time-of-flight mass spectrometry (GCxGC–TOF MS) provides efficient non-target screening of organic pollutants in water.

Evaluating the authenticity of brand perfumes by GC×GC‒TOF MS with Tandem Ionisation

Tandem Ionisation (both hard and soft ionisation in a single analysis) with GC×GC–TOF MS enables the separation of structurally similar compounds in perfume samples (such as terpenes, which are difficult to speciate). This enables the detection of subtle differences between brand and imitation perfumes in authenticity tests.

Non-target screening of liquid smoke flavourings by GC×GC‒TOF MS

The use of comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GC×GC–TOF MS) for improved separation and confident chemical fingerprinting of liquid smoke composition.

Chemical fingerprinting of petroleum products using GC×GC–FID/TOF MS

Comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GC×GC–TOF MS) is the ideal platform for the analysis of complex petrochemical samples, and thanks to advances in both hardware and software, data exploration, filtering and mining no longer need to be complex.

Uncovering hidden compositional changes in breath profiles using untargeted chemometric workflows

Thermal desorption (TD)–GC×GC–TOF MS can lead to a greater insight into the volatile organic compounds emitted in breath than TD–GC–TOF MS, producing a large amount of complex data. With a powerful chemometrics platform, the data can be transformed into meaningful results.

Improved identification of organic markers in ambient particulate matter (PM2.5) for reliable source attribution

Here, we demonstrate how direct thermal desorption (TD) of PM2.5 filters offers a streamlined solution to sample preparation, while enhanced separation and sensitive detection by comprehensive two-dimensional gas chromatography coupled with time-of-flight mass spectrometry (GC×GC–TOF MS) offers improved sample characterisation for organic components.
