Characterisation of Allergens in Cosmetics by GC×GC–TOF MS with Select-eV Variable-Energy Electron Ionisation

This application note shows that BenchTOF instruments, coupled with GC×GC, can provide a high-performance solution for the detection and quantitation of allergens in complex cosmetics extracts. Revolutionary variable-energy electron ionization technology was also shown to enhance both the sensitivity and selectivity of analyses by generating mass spectra containing structurally-significant fragment ions with an improved molecular ion signal.
