    Abstract: Alcohol content of subject''s breath is determined by flowing a breath sample over a combusting surface, provided by a heated catalyst, to cause oxidation of the alcohol constituent which, in turn, produces oxyluminescence or light emission of a magnitude directly proportional to the alcohol concentration. A lightresponsive device, such as a photomultiplier, effectively converts the oxyluminescence to an electrical information signal whose amplitude accurately represents the breath alcohol concentration.
