Sepax Polar Phases for Hydrophilic Interaction Chromatography (HILIC) - a Series of chemistries of weak acidic, neutral, and basic stationary phases for separating basic, neutral and acidic compounds of high polarity by the separation mode of HILIC. Sepax Polar phases have been innovatively and specially designed to ensure maximum surface coverage, resulting in high stability of the stationary phases. The chemistry of monolayer formation is completely controlled that results in very reliable lot-to-lot and column-to-column reproducibility. The uniform, spherical silica particles have a nominal surface area of 300m2/g with a controlled pore size of 120Å. Sepax Polar-100 and Polar-Diol are neutral, polar phases, while Polar-Diol is more polar than Polar-100. Polar-Silica is a weak acidic phase. Polar-Pyridine and Polar-Imidazole are basic phases, while Polar-Imidazole phase is more basic than Polar-Pyridine phase. |
