TL;DR: In this article, cycloaliphatic poly(ether urethane) has been used as a sensitive layer for the detection of organic solvent vapours such as ketones, alcohols, amines, alkanes, aromatic compounds and chlorinated hydrocarbons with quartz microbalances (QMB), interdigital capacitors (IDC) and calorimetric transducers.
Abstract: Cycloaliphatic poly(ether urethane) has been used as a sensitive layer for the detection of organic solvent vapours such as ketones, alcohols, amines, alkanes, aromatic compounds and chlorinated hydrocarbons with quartz microbalances (QMB), interdigital capacitors (IDC) and calorimetric transducers. The sensor signals are completely reversible and reproducible at room temperature. Using QMBs, even less than 10 ppm of nitrobenzene in air can be detected. The IDC measurements show particularly high sensitivities for alcohols. The different transducer parameters are discussed comparatively for the different organic volatiles.

TL;DR: In this article, the surface diffusion of strongly adsorbing hydrocarbon vapours on activated carbon was measured by using a constant molar flow method, where pure adsorbate is introduced into a semi-batch adsorber at a constant flow rate.

TL;DR: In this paper, a multi-channel piezoelectric (PZ) quartz crystal detection system with a home-made computer interface was prepared and employed to detect various organic molecules in a flow system.
