Characterisation of Allergens in Cosmetics by GC×GC–TOF MS with Select-eV Variable-Energy Electron Ionisation
28 May 2014This 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.

Mass SpectrometryMass spectrometry (MS) is a powerful analytical technique used to identify and quantify molecules based on the mass-to-charge ratio of gas-phase ions. It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place.
