While modern labs often use Gas Chromatography (GC) for blood alcohol analysis, older chemical methods like the Kozelka and Hine test are historically significant and still valid for demonstrating the principles of alcohol detection.
Step 1: Identify the test. The Kozelka and Hine test is a classic chemical method used in forensic toxicology.
Step 2: Determine its purpose. It is a distillation and oxidation-reduction titration method for the quantitative determination of alcohol (specifically ethanol) in blood and other biological fluids.
Step 3: Conclude. The test is specifically designed to measure blood alcohol concentration.
