Profiling of fragrance components and potential allergens

contributed by Markes International Ltd | 07/03/2013

In this Application Note we describe the use of a continuously-sampling thermal desorber in conjunction with GC/TOF MS to monitor the build-up and decay of fragrances and potential allergens released into indoor air from a plug-in air freshener.

Air fresheners emit numerous volatile organic compounds (VOCs), amongst which are many fragrance compounds. Developing a near-real-time method of monitoring their build-up and decay in indoor air is of potential interest for manufacturers when formulating their products. Such studies are of particular value in light of a report showing the presence of carcinogens, allergens and other hazardous VOCs amongst the fragrance components in air fresheners1. In this Application Note we look at the near-real-time (NRT) analysis of the compounds released from a plug-in air freshener, using the TT24-7™ Series 2 thermal desorber combined with gas chromatography (GC) and time-of-flight mass spectrometry (TOF MS). The fragrance was allowed to diffuse into a room, and the air was sampled continuously to monitor the compounds released as their concentrations changed over time.
