A methylene blue active substances assay, or MBAS assay, is a colorimetric analysis test method that uses methylene blue to detect the presence of anionic surfactants (such as a detergent or foaming agent) in a sample of water. An anionic surfactant detected by the color reaction is called a methylene blue active substance (MBAS). After first acidifying a water sample (with boric acid, for example), one adds to it chloroform and a Web1 jun. 2024 · Sep 2024 - Present2 years 8 months. Saskatoon, Saskatchewan, Canada.
