Ultisil XB-NH2, 5μm, 21.2×250mm, 120Å Buy Online Cheap Pice

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 XB-NH2 column is typically used for the separation of various monosaccharides under reversed-phase conditions. However, it is not recommended for analyzing compounds containing aldehyde or carbonyl groups, as well as reducing sugars.

Under normal-phase elution conditions, it is suitable for analyzing polar compounds, tocopherols, and certain organic compounds soluble in alkanes, alkenes, and aromatic hydrocarbons.
