Fragrance

The large number of often structurally similar compounds in fragranced products demands the high degree of separation only available with GC×GC, coupled with advanced TOF MS detection techniques such as Tandem Ionisation.

Evaluating the authenticity of branded perfumes

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

Enhanced separation of hop oils by flow-modulated GC×GC–TOF MS

This study demonstrates the high performance of a flow-modulated GC×GC–MS system for the evaluation of complex hop oils, which allows effective modulation of even the most volatile components without the need for expensive liquid cryogen. Analyte speciation is also aided by Tandem Ionisation for simultaneous acquisition of hard and soft EI data.

Tackling the extended list of fragrance allergens by flow-modulated GC×GC–TOF MS

This study investigates the use of flow-modulated GC×GC to analyse an 84-component allergen calibration standard, with simultaneous detection by TOF MS for confident identification and FID for robust quantitation. The validity of the method is then demonstrated with the examples of essential oils and a fragrance mix.
