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.
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.
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.
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.
