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.
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).
