A polydimethylsiloxane micromolded separation column is presented with monolithically integrated gas injection, temperature control, and a nanomaterial chemiresistor array for multiparametric gas detection in complex mixtures on a unique single chip platform. Sensor arrays are made of carbon nanotubes, vanadium oxide, and reduced graphene oxide nanomaterials. The functionality of a micromolded gas...
Current gas sensors are mainly categorized into two modes of operation; chemical type operating by gas adsorption and physical type using ionization method. Chemical type conductivity-based gas detectors are large in size, they operate at high temperatures, and their response time is slow. Moreover most of them are only capable of detecting single type gases due to their low selectivity. Physical...
