Ultisil HILIC Silica, 10µm, 30×250mm, 120Å Sale Browse

Welch preparative column uses the same packing materials as does analytical column, to ensure the best reproducibility of analysis and preparative scale. Special packing technique and stainless modular column tube ensure the stability of column bed. The theoretical plate number for 10 μm column is greater than 35000/m; for 5 μm column, it is greater than 75000/m, and the peak symmetry is around 0.95~1.20.

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.
