HPLC Separation of the Nonionic Surfactant Triton-X-100

Triton X-100 is a non-ionic surfactant which has a hydrophilic polyethylene oxide group (on average it has 9.5 ethylene oxide units), and a hydrocarbon lipophilic or hydrophobic group. SHARC 1 HPLC columns are used to separate oligomers of Triton X-100. Separation is achieved in anhydrous conditions by hydrogen bonding using acetonitrile (ACN) and methanol (MeOH) as the mobile phase with formic acid and ammonium formate (AmFm) as buffer. This method can be used in determination of oligomers of Triton X-100 in detergents, liquid, paste, and powdered cleaning formulations. This separation can be monitored with almost any detection technique (UV, ELSD, LC/MS, RI, CAD, etc.)
