How the Hexavalent Chromium Detection Test Swab Works
Simply squeeze the swab to break both ampules, shake to mix, and wipe the moistened tip across the suspect surface. If hexavalent chromium is present, the tip turns pink or purple. The darker the colour, the higher the Cr(VI) concentration, giving you an immediate, visual risk assessment with no guesswork.
