Abstract
This article presents a gas chromatography (GC) based solution for the online detection of contaminants in plastics recycling. The goal is to continuously assess post-consumer recycled plastics for adaptive treatment by stripping odorous substances and other contaminants in a compounding step. Based on earlier work, an automated sample transfer to a purpose-built GC setup has been devised. Steep heating rates and cooling rates exceeding −100 Kmin-1 allow for fast repetition of measurements and the inte-grated GC detector enables accurate peak reconstruction for dense short-column chromatograms.
