  Zodiac HST Series Zodiac HST Series offers advanced mixed-mode stationary phases, designed to take chromatography beyond traditional separation techniques. Unlike conventional liquid chromatography methods that eliminate “unwanted” interactions, our columns harness the power of multiple interactions on the stationary phase, offering enhanced versatility. With a unique combination of hydrophobic and ion-exchange functionalities, Zodiac HST columns allow for the independent control of the retention of ionizable, neutral and non-polar compounds, optimizing separation based on mobile phase Operation. This innovative technology enables complex separations by simply adjusting the amount of organic modifier and acid in the mobile phase. Whether utilizing reverse-phase, ion-exchange, ion-exclusion, or size-exclusion mechanisms, Zodiac HST columns perform seamlessly, providing high retention of polar compounds and eliminating the need for ion-pairing reagents. Perfect for complex and div...
