Web15. mar 2024 · These two coupled reactions produce an electrical current between the electrodes that’s proportional to the amount of ethanol present in your breath. So, breathalyzers don’t truly measure blood alcohol content (which can only be done with a blood test) but estimate it based on the ethanol in your breath. There are a few situations … Photovoltaic assay The photovoltaic assay, used only in the dated photoelectric intoximeter, is a form of breath testing rarely encountered today. The process works by using photocells to analyze the color change of a redox (oxidation-reduction) reaction. A breath sample is bubbled through an aqueous solution of sulfuric acid, potassium dichromate, and silver nitrate. The silver nitrate acts as a catalyst, allowing the alcohol to be oxidized at an appreciable rate. The requisit…
