  • Title: Concentration verification of ethanol/nitrogen compressed gas cylinders prior to use for periodic determinations of accuracy in California.
    Author: Matthias DJ, Harvey DC, DeFraga DE.
    Journal: J Anal Toxicol; 2001 Apr; 25(3):215-8. PubMed ID: 11327355.
    Abstract:
    A method that uses compressed gas ethanol breath standard (EBS) cylinders to perform periodic determinations of accuracy on evidential breath alcohol instruments in California was developed. To use EBS cylinders, the California State Department of Health Services required verification of the ethanol content of the EBS cylinders using an infrared method. The infrared method developed employs a modified Alcotest 7110 MK III-C manufactured by National Draeger, Inc. that functions at the 9.5-mm wavelength of the infrared spectrum. Criteria and methodology for verifying EBS cylinder ethanol concentrations are described.
