Kid Approved Ultisil Aq-c18, 10μm, 30×250mm, 120Å (top Rated) [w4j7aPgr]

Welch preparative column uses the same packing materials as does analytical column, to ensure the best reproducibility of analysis and preparative scale. Special packing technique and stainless modular column tube ensure the stability of column bed. The theoretical plate number for 10 μm column is greater than 35000/m; for 5 μm column, it is greater than 75000/m, and the peak symmetry is around 0.95~1.20.

Ultisil AQ-C18 is a HPLC column designed to withstand 100%–0% aqueous environments. It features a polar group as the endcapping reagent, with moderate carbon loading and low alkyl chain bonding density, offering moderate retention. Compared to XB-C18, it has a weaker ability to adsorb impurities. This column is ideal for the analysis of polar samples, such as water-soluble vitamins, amino acids, and other hydrophilic compounds.
