A Rapid Method for Blood Alcohol Determination by Headspace Analysis Using an Electrochemical Detector
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.
