Abstract
An ionic liquid bound on an exposed surface of a device such as for detecting organic chemicals, preferably a gas sensor is described. The gas sensor can operate at high temperatures with a fast linear response which is also reversible. At high temperatures, the frequency change (Δf) versus concentration (C) curve mirrors the Henry's gas law, such that the concentration of a gas sample in liquid solvent is proportional to the concentration or partial pressure of the sample in gas phase. A single gas sensor, or an array of sensors, can be used for the detection and quantitative analysis of gas vapors.
