Evaluating the authenticity of branded perfumes

This study demonstrates how the comprehensive data acquired using GCxGC–TOF MS with Tandem Ionisation® can be processed in a single, automated workflow to uncover the subtle differences between brand and imitation fragrances.

The global perfumes market was valued at over $30 billion in 2019 and is expected to continue growing. However, this has been accompanied by a rise in imitation fragrances, sold at significantly lower prices compared to the luxury brands. Their packaging is often so similar that consumers may be unable to distinguish between the genuine and imitation goods.

The diverse range of chemical classes in perfumes requires advanced separations to resolve co-elutions and provide identification of the analytes present. Here, GCxGC is combined with the BenchTOF2™ mass spectrometer, which has the benefit of Tandem Ionisation to provide both hard and soft EI data in a single analysis. The complementary soft EI spectra improves chemical selectivity to enhance untargeted ‘discovery’ workflows, as required in quality and authenticity evaluation, where you may not know what compounds can be used to differentiate between genuine and imitation products.
