Welch Materials UHPLC Guard Column Cartridge Ultisil AQ-C18, 4 x 5 mm, 2 pc/PAK

Name: Welch Materials UHPLC Guard Column Cartridge Ultisil AQ-C18, 4 x 5 mm, 2 pc/PAK
Brand: Welch Materials

Ultisil AQ-C18 columns are designed to have extended retention and selectivity for hydrophilic and polar compounds, which are poorly or not at all retained on other phases. A proprietary bonding chemistry, Ultisil AQ-C18 avoids so-called “phase collapse”, even when 100% water is used, a phenomenon that conventional C18 columns typically exhibit at high water content in the mobile phase. Ultisil AQ-C18 phase is fully end-capped to ensure the best peak shapes of polar and basic compounds and longer lifetime. Typical applications are separations of water soluble compounds that cannot be retained on traditional C18 phase.Show more
