Ultisil Diol, Semi-Prep Cartridge: 10µm, 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 Diol is a normal-phase column offering superior stability and reproducibility compared to silica and amino columns, as well as enhanced selectivity and peak shape. Its unique bonding technology ensures stable stationary phase structure, while strict manufacturing processes guarantee excellent batch-to-batch reproducibility.
