Abstract
An apparatus is provided for the detection of changes in concentrations or amounts of components of a fluid mixture by measuring changes in an electrical or a mechanical property of a sensing element when the sensing element is exposed to the fluid mixture. The preferred property of the sensing element to be measured is its electrical resistance which changes when the sensing element adsorbs at least one component of the fluid mixture.
