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.
开发了一种使用压缩气体乙醇呼气标准（EBS）钢瓶对加利福尼亚州的呼气酒精证据检测仪器进行定期准确性测定的方法。为了使用EBS钢瓶，加利福尼亚州卫生服务部要求使用红外方法对EBS钢瓶中的乙醇含量进行验证。所开发的红外方法采用了由德国德尔格公司制造的经过改良的Alcotest 7110 MK III-C，其在红外光谱的9.5毫米波长下运行。文中描述了验证EBS钢瓶乙醇浓度的标准和方法。
