The CHEMetrics test kits for for the determination of Detergents (anionic surfactants, MBAS) in aqueous solutions are based on patented Self-Filling Reagent Ampoule technology, and employ the Methylene Blue method. Premixed. Premeasured. Precise. Each CHEMets kit contains 30 tests (Vacu-vials contain 20 tests). Suitable for pharmaceutical industry as well as residential water testing.
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-coloured complex that is extracted into an immiscible organic solvent. Results are expressed in ppm (mg/l) as linear alkylbenzene sulphonate (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.
Cleaning validation is a requirement in industries such as pharmaceutical manufacturing which adhere to Good Manufacturing Practice (GMP) and Quality Systems Regulations (QSR), and is specific to the cleaning method and agent employed. A cleaning validation involves testing for acceptable residue on pharmaceutical manufacturing or medical device surfaces. CHEMetrics® Detergents Test Kit, Cat. No. K-9400, featuring a superior extraction/sampling technique, is routinely used by pharmaceutical companies to measure detergents (anionic surfactants) to ensure that no excessive residual surfactant remains.
