Potential artefacts from using porous polymers for collecting aroma components

Abstract
Examination of the components produced by heating Porapak Q and Tenax GC above their normal operating temperatures revealed the presence of hydrocarbons, benzaldehyde, ethylbenzaldehyde, acetophenone, ethylacetophenone, isopropylbenzyl alcohols, diacetylbenzene, phenol and furans, all of which could potentially occur as artefacts when using these porous polymers for collecting and concentrating aroma components from foods.
