Formaldehyde Information


The K-4605C Formaldehyde Kit was designed to accurately measure the levels of Formaldehyde in water from 0-1200 ppm and 1200-12,000 ppm. K-4605C uses the Purpald Method. Purpald® is subject to fewer interferences than Schiff's reagent or chromotropic acid procedures. A purple-colored complex is formed when Purpald in alkaline solution reacts with formaldehyde. Results are expressed as ppm (mg/L) CH2O.

Shelf-life of the Purpald Reagent: five months. We recommend stocking quantities that will be used within four months.

R-4605C Refill Package includes 30 tests and can be purchased separately.
