The introduction of electrochemical sensors for the detection and analysis of volatile substances, in particular low concentrations of ethyl alcohol in the vapor phase, has led to the development of a range of breath alcohol instruments based on this principle . The Alcolmeter Evidential Device is a breath-testing instrument that aspirates a sample of breath or vapor into an electrochemical cell for quantitative oxidation of ethanol . The same device could well be used for headspace analysis of ethanol in biological materials, enabling rapid, on-the-spot screening of samples and even quantitative blood alcohol determinations.
