The experiments have been carried out with ethanol (EtOH) and show response times as low as 30 s under VOC-saturated atmospheres, and the estimated limit of detection is below 4000 ppm for both sensor types. The selectivity towards other VOCs is relatively poor, although the dynamics of adsorption/desorption differ for each VOC and could be used for selectivity purposes. Furthermore, the hydrophobicity of ZIF-8 has been confirmed and the fabricated sensors are insensitive to this compound, which is a very attractive result for its practical use in gas sensing devices.13 p.application/pdfengcc-by (c) Estany-Macià, A. et al., 2024http://creativecommons.org/licenses/by/4.0/Detectors òpticsDetectors de gasosInterferòmetresOptical detectorsGas detectorsInterferometersinfo:eu-repo/semantics/article7501442025-07-28info:eu-repo/semantics/openAccess
