Designed for professional use, these HPLC columns are specifically engineered for Hydrophilic Interaction Chromatography (HILC). Featuring a zwitterionic surface chemistry, they are ideal for separating highly polar analytes such as amino acids, peptides, and water-soluble vitamins. With a particle size of 1.8 microns and a pore size of 110 Angstroms, these UHPLC columns offer excellent pressure stability up to 900 bar and temperature stability up to 60 degrees Celsius. The columns have a specific surface area of 340 square meters per gram, ensuring efficient separation. They come in a length of 75 millimeters, with an inner diameter of 2 millimeters, and a total volume of 0.22 milliliters. This HILIC column is compatible with
