· Separation type: Liquid Chromatography Mixed-mode · Method for Analysis of Benzalkonium chloride on Primesep SB by SIELC Technologies
Benzalkonium chloride, also known as Zephiran or Alkyldimethylbenzylammonium chloride, is a positively charged surfactant often used as a pharmaceutical preservative and as an antiseptic. Benzalkonium Chloride can be retained on a mixed-mode stationary phase Primesep SB column with embedded strong basic ion-pairing groups, using a gradient analytical method with a simple mobile phase of water, Acetonitrile (MeCN), and a Sulfuric acid (H2SO4) ionic modifier. This analysis method can be UV detected at 210 nm with high resolution and peak symmetry.
