Acclaim Surfactant Column for separating all classes of Surfactants

Are you tired of the broad tailing peaks you get when separating cationic surfactants using reversed phase columns? Would you like to be able to separate all classes of surfactant using a single column? Introducing the Acclaim Surfactant column; the only column developed specifically for the analysis of surfactants.

  • Ideal selectivity for mixtures of surfactants
  • Excellent peak shapes for cationic surfactants
  • Compatible with highly aqueous mobile phases
  • Improved resolution for ethoxylated surfactants
  • Rugged separations under a variety of conditions
  • Methods compatible with various detectors
  • Broad range of applications.

When analyzing cationic surfactants by reversed phase chromatography, it is often difficult to obtain sharp, symmetrical peaks due primarily to the presence of free silanols on the silica. The Acclaim Surfactant columns feature a novel bonding chemistry that allows for effective deactivation of free silanols towards positively charged cationic surfactants, resulting in excellent peaks shapes.

The Acclaim Surfactant column provides excellent resolution of surfactants over a broad range of applications using detectors ranging from UV-Vis, to suppressed conductivity, to evaporative light scattering (ELSD), to mass spectrometry. As a consequence of its novel chemistry, it exhibits a unique polarity that provides significantly improved resolution for individual oligomers of ethoxylated surfactants compared with conventional C18. The Acclaim Surfactant is also resistant to dewetting under highly aqueous mobile phase conditions, and thus can be used to provide excellent resolution between strongly hydrophilic compounds, such as isomers of xylene sulfonate.

Each Acclaim Surfactant column is manufactured to stringent specifications to ensure column-to-column reproducibility. Each column is shipped with a lot validation sheet showing the test results and specifications for the lot of bonded silica Production columns are individually tested for capacity and efficiency, and closely monitored for metals contamination. Reproducible column-to-column manufacturing, the use of ultrapure silica, and performance validation of every column prior to shipping, all ensure that the quality of your separations will be maintained month to month and year to year.
