Agilent J&W DB-XLB Capillary Column Application Note for GC/MS Allergen Analysis

About this manual

The document describes a method to detect 24 European Union (EU) regulated flavor and fragrance allergens in essential oils used for aromatherapy. It highlights the use of Gas Chromatography-Mass Spectrometry (GC/MS) coupled with an Agilent J&W DB-XLB capillary column, which offers unique selectivity to resolve these analytes from complex oil matrices.

The note details the experimental setup, including specific chromatographic conditions and flow path supplies used on an Agilent 7890A GC System. It presents results showing the detection of allergens in ylang ylang, lavender, and eucalyptus oils, demonstrating that the method can identify potential allergens at levels significantly higher than typical cosmetic limits.
