Abstract |
A method of analyzing seized/suspected beverages for their alcohol content using the Intoxilyzer® 5000C or the Alcotest® 7410 GLC is reported. The accuracy of alcohol content on the labels of commercially sold beverages was also examined. Wines, beers and liquors (n = 21) bought from the open market were analyzed by headspace gas chromatography (GC). The data were compared with those obtained from using the Intoxilyzer® 5000C or Alcotest® 7410 GLC. With the latter two instruments, the headspace vapour of diluted beverages was blown into the calibrated instrument through the simulator. The results obtained by the latter two instruments were within ±6% of those obtained using the GC method. The labeled alcohol concentrations were within ±5% of the values measured by GC. They can, therefore, be used as the basis for blood alcohol concentration calculations. |
