iHILIC®-(P) Classic, HILIC HPLC Guard Column pH stabil

iHILIC columns are designed for the separation and purification of polar and hydrophilic compounds using Hydrophilic Interaction Liquid Chromatography (HILIC). The packed iHILIC®-(P) Classic stationary phase is charge modulated diol polymer particles, which are covalently bonded with neutral, positively charged, and negatively charged hydrophilic functional groups. Therefore, its separation mechanism is based on a combination of hydrophilic interaction, hydrogen bonding, and weak electrostatic interactions. It has unique separation selectivity and high separation efficiency. Compared to silica base HILIC materials, polymeric iHILIC®-(P) Classic can stand much higher pH.
