Instrument for the determination of ethanol in breath in law-enforcement practice. Paper presented at the 23rd Annual Meeting of the American Academy of Forensic Sciences, Phoenix, Arizona, 1971.

The Omicron Intoxilyzer has been described which relies on infrared absorption of energy by ethyl alcohol vapours in breath samples. There is no chemical to handle, and the technique is rapid and simple to administer. Digital display and hard copy printout by a tamper-proof printer will provide the courts with a strong tool to enforce new driving laws.
