          Acclaim Surfactant LC Columns

          Outstanding Separation of All Classes of Surfactants

          The Thermo Scientific  Acclaim? Surfactant columns are high-efficiency silica-based HPLC columns for separating a wide variety of surfactants, including anionic, cationic, nonionic, and amphoteric surfactants. Due to their novel chemistry, these columns exhibit a unique polarity that provides significantly improved resolution for individual oligomers of ethoxylated surfactants, compared with conventional C18 columns.

          • Ideal selectivity for simultaneous separation of anionic, nonionic, cationic, and amphoteric surfactants
          • Well suited for the determination of cationic surfactants
          • Capable of retaining highly hydrophilic compounds, such as hydrotropes
          • Excellent resolution for ethoxylated surfactants
          • Rugged separations under a variety of conditions
          • Methods compatible with various ELSD or UV detectors

          The Acclaim Surfactant columns can be used with evaporative light scattering detectors (ELSD), suppressed conductivity detectors (SCD), and UV-Vis detectors (UV).  These columns are resistant to dewetting under highly aqueous phase conditions, and thus can be used to provide excellent resolution between strongly hydrophilic compounds, such as isomers of xylene sulfonate.

          Broad Range of Applications

          Surfactants are widely used in industrial, agricultural, and pharmaceutical markets, and in products as diverse as pesticides, detergents powders, petroleum products, cosmetics, and pharmaceuticals. The Acclaim Surfactant columns have been designed specifically for the HPLC separation of these surfactants.

          The Acclaim Surfactant columns can be used for the HPLC separation of anionic surfactants (alkylbenzenesulfonates, alkyl sulfates, alkylether sulfates) and cationic surfactants (alkyl quaternary ammonium salts, benzylalkylammonium salts, pyridinium salts, and quaternary imidazolium compounds) nonionic surfactants, and polyethylene glycols (PEGs).
