Abstract
This study introduces a thick film metal oxide semiconductor (MOS) sensor as a promising alternative to traditional gas chromatography (GC) detectors. A gas mixing apparatus was used to simulate gas elution from a GC column with a custom measurement chamber for optimal coupling of sensor and gas flow. The experiments achieved precise quantification of ethanol at concentrations in the ppb range, utilizing a MOS sensor temperature profile for sensitive peak detection. The results show that MOS sensors offer a cost-effective and reliable substitute for traditional GC detectors in analytical applications.
