Ultisil HILIC Silica, Prep Cartridge: 5µm, 120Å, 30×10mm

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 Hilic Silica features a specially treated silica matrix to enhance lifespan and stability when separating strongly polar compounds in high aqueous phases. It operates under multiple retention mechanisms in HILIC mode, offering complementary selectivity to reversed-phase chromatography for unique separation results. The column is optimized for high-volatility mobile phases (>80% organic solvent), making it ideal for mass spectrometry (MS) detection and sensitivity analysis.
