## Abstract An improved set‐up for solid‐phase extraction with thermal desorption coupled on‐line to gas chromatography (SPETD‐GC) is presented. It includes a newly designed liner for a programmable temperature vaporizer (PTV) and an improved water elimination system. The SPETD procedure now includ
