Anionic surfactants which are contaminated from factory wastewater and domestic sewage are considered to be an important indicator of water pollution because they cause foaming when present in water. Linear alkylbenzene sulfonic acid (LAS), a kind of anionic surfactant, is used in the largest amount among synthetic detergents. For anionic surfactants, standard values are set for Drinking Water Quality Standards and Environmental Quality Standards for Water Pollution in Japan.
Fujifilm Wako provides various standard solutions for anionic surfactants that are subject to measurement in Japanese Drinking Water Quality Standards, internal standard solutions that can be used for LC/MS, and HPLC columns.
