Welch Materials Ultisil AQ-C18 Columns

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.

Ultisil Series HPLC Columns are based on ultra-pure (purity > 99.999%) spherical and totally porous silica, unique bonding chemistry and proprietary surface modification techniques, producing excellent peak shape, column efficiency and exceptional lot-to-lot reproducibility. Ultisil column is the best choice for method development. owing to complete bonding chemistries and stable performance.

Features

Ultra-pure spherical porous silica, purity > 99.999%
Wide pH range: 2.0-8.0
High efficiency: theoretical plate > 80000/m
Excellent peak symmetry: tailing factor=0.95~1.05
Exceptional lot-to-lot reproducibility
