R-9400 Detergents

K-9400 Detergents CHEMETS Kit is used to determine Detergent levels from 0-3 ppm.

Detergents Information


The K-9400 Detergents Kit was designed to accurately measure the Detergent levels in water from 0-3 ppm. K-9400 uses the Methylene Blue Method. The methylene blue active substances (MBAS) method is used in a 3-minute procedure to measure anionic detergents in the 0-3 ppm (mg/L) range. The procedure features a unique extraction/sampling technique that eliminates several steps required in other test procedures and provides increased sensitivity. Anionic detergents react with methylene blue to form a blue-colored complex that is extracted into an immiscible organic solvent. Results are expressed in ppm (mg/L) as linear alkylbenzene sulfonate (LAS), equivalent weight 325.

Detergents can be introduced into the water supply by industry, soap manufacturers, and private households. Environmental analysts often include a determination of anionic detergents when assessing surface water pollution.

R-9400 Refill Package includes 30 tests and can be purchased separately.
