Comprehensive Characterization of Essential Oil by GC×GC–TOF MS

This application note shows that BenchTOF time-of-flight mass spectrometers, in conjunction with GC×GC, provide a high performance solution for comprehensively screening the total composition of essential oils. Essential oils, due to their desirable aromatic qualities, are used as raw materials in the production of a wide range of cosmetic products, including fragrances and personal care products. The chemical composition of many essential oils exhibits a degree of natural variation, but even minor changes can adversely affect the quality of the final product. Rigorous quality control procedures are therefore needed to ensure that essential oils do not vary significantly from the initial reference batch, or contain any unwanted adulterants.
