These high-efficiency, silica-based columns provide excellent resolution and throughput for HPLC separations using  UV-Vis, evaporative light scattering (ELSD) or refractive index (RI) detection. The novel surface chemistry creates a unique polarity that offers significantly improved resolution for individual oligomers of ethoxylated surfactants compared with conventional C18 columns.

• Ideal selectivity for separation of anionic, nonionic, cationic and amphoteric surfactants
• Resistant to dewetting or phase collapse under highly aqueous mobile phase conditions
• Retains highly hydrophilic compounds, such as hydrotropes
• Excellent peak shapes, especially for cationic surfactants
• Rugged separations under a variety of conditions
