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 separation device as opposed to the conventional etched silicon μGC column opens the door to disposable, easily manufactured, stand-alone gas chromatography for clinical diagnostics or remote fieldwork. Combining separation column with a diverse nanomaterial sensor array provides multiparametric detection of gases in a single chip device. The device has the dimensions of a glass slide while drawing <;2 W of power and capable of separation and detection of gases verified using a standard analytical mixture of aliphatic compounds.
