Analysis of Ethanol in Blood with Agilent 7820A GC and 7697A Headspace Sampler

The Agilent 7820 GC and 7697A headspace is an economical instrument configuration for measuring ethanol in blood. The full EPC control from auto sampler to detector ensures good repeatability and simple-to-use operation, which is ideal for a routine QA/QC lab. According to the national standard, drunk driving is defined as the concenatration of ethanol in the blood of 80 mg/ 100 mL or more, while drinking and driving is defined as the concentration of ethanol in the blood of 20 mg/ 100 mL or more. To meet this quantitative requirement, the calibration curve for method was generated in a wide range of 10 mg/ 100 mL to 160 mL/ 100 mL so that both limits could be identified.
