How do you separate blood from alcohol?

To separate blood from alcohol, a common method is to use a process called centrifugation, which involves spinning the blood at high speeds to separate its components based on density. The alcohol content can then be analyzed from the plasma or serum portion, while the cellular components settle at the bottom. Additionally, enzymatic assays or gas chromatography can be employed to quantify the alcohol concentration in the separated plasma. It's important to handle the samples properly to avoid contamination and ensure accurate results.
