HPLC Separation of Alkyl Sulfonic Acids
Alkyl sulphonic acids are used as surfactant additives in many products. Homologs of linear alkyl sulfonates are separated on a Primesep 500 mixed-mode cation exchange column in reversed-phase anion-exclusion mode. This generic method can be used for determination of alkyl sulfonates in detergents, soaps, etc.
