Primesep Mixed-Mode HPLC Columns from SiELC

The Primesep family of mixed-mode HPLC columns from SiELC offers a wide variety of stationary phases, boasting unprecedented selectivity in the separation of a broad class of chemical compounds across multiple applications. The Primesep stationary phases contains two major interactions, and they are independently adjustable with mobile phase selection. The hydrophobic interaction is controlled by the amount of organic modifier in the mobile phase, while the ion exchange interaction is controlled by the ion strength and pH of the mobile phase. This unique property allows using one stationary phase for a vast application range, including simultaneous analysis of polar and non-polar compounds, ionizable and neutral compounds, and organic and inorganic compounds.
