The purpose of this study was twofold; to identify possible marker molecules released from preservative-treated wood upon heat treatment and then develop a prototype detector for this marker. Two methods for heating the samples were used: Pyrolysis combined with Gas-Chromatography with IR-detection and Thermal Desorption combined with Gas-Chromatography with mass detection. A first prototype detector was developed and tested for the detection of VOCs released from creosoted and organic type preservative treated wood.
