Figure 3. An example of a typical experiment using the permanganate-PA method to detect the different alcohols in saliva.

Figure 3

The concentration of the individual alcohols was varied from 10 to 100 mg/dl. Methanol and ethylene glycol produced a blue hue at a concentration of 10 mg/dl which increased in intensity at higher concentrations. A blue hue appeared with ethanol and diethylene glycol at a concentration ~ 50 mg/dl. No color was detected with the water (WB) and saliva (SB) controls and isopropanol.
