Ultisil LP-C18, Prep Cartridge: 5µm, 120Å, 21.2×10mm

Welch preparative guard column cartridges use the same packing as the preparative column, which can intercept some of the same polar substances in the sample and prevent them from contaminating and damaging the packing materials in the preparative column. 10×10mm cartridge holder: 00808-01116, 21.2×10mm cartridge holder: 00808-01106, 30×10mm cartridge holder: 00808-01117, 50×10mm cartridge holder: 00808-01110.

Ultisil LP-C18 column is a HPLC column designed to withstand 100% aqueous to 100% organic solvents. It features steric hindrance side-chain protection to shield hydroxyl groups and adopts a non-endcapped process. With strong spatial selectivity, it exhibits high orthogonality to conventional C18 columns, making it a suitable alternative for analytes that are difficult to separate on standard C18 columns. It demonstrates low stationary phase bleed under strongly acidic conditions, as an ideal baseline noise can be observed even when using an ELSD detector.
