AppNote 264: Analysis of Scented Crayons Using Direct Thermal Extraction with Gas Chromatography-Mass Spectrometry

Abstract

Scented products, including car air fresheners, soaps and detergents, candles, and even garbage bags, are ubiquitous in our everyday lives. They are primarily intended to cover up malodors but can also enhance one’s mood or be used in aromatherapy.


Thermal desorption is an introduction technique for gas chromatography that can be used for a wide variety of applications, including the analysis of fragrance compounds in consumer products. Options for thermal desorption include direct thermal extraction, Twister, Thin Film SPME, air sampling, and direct injection of liquids.


For scented products, the level of fragrance compounds in the product may need to be determined for quality control purposes or to see how long the compounds stay active (shelf life). Other components of scented products can also be determined using thermal desorption techniques.


This study used direct thermal extraction to determine fragrance compounds in scented crayons purchased at a local store.
