Welch Materials Ultisil DLC HILIC Amphion II UHPLC Column, 1.8 µm, 120 Å, 2.1 x 100 mm - H00274-11912

The diamond coating technology enhances the inner surface of the chromatography column with strong hydrophobicity, which overcomes the adverse effects of the column wall on separation.The high hardness and significant tensile properties of the diamond coating resolve the conflict between column mechanical strength and the influence of metal ions on separation. DLC HPLC Columns are ideal for preparation and purification of biological samples, such as proteins, polysaccharides, and nucleic acids.

Ultisil UHPLC HILIC Amphion II column features a zwitterionic (amphion) structure containing both positively and negatively charged centers. This unique composition significantly enhances the retention of acidic and basic compounds through ion-exchange mechanisms. With excellent hydrophilicity, this stationary phase enables effective HILIC-mode separation of polar, hydrophilic small molecules and basic compounds. Compared to traditional silica- and amino-based HILIC materials, it offers superior reproducibility and more stable HILIC separation performance.
