Welch Materials Ultisil XB-NH2 Columns

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.

Ultisil Series HPLC Columns are based on ultra-pure (purity > 99.999%) spherical and totally porous silica, unique bonding chemistry and proprietary surface modification techniques, producing excellent peak shape, column efficiency and exceptional lot-to-lot reproducibility. Ultisil column is the best choice for method development. owing to complete bonding chemistries and stable performance.
