Since most amino acids have no absorption or only weak absorption in the ultraviolet region, in order to improve the sensitivity and separation selectivity, amino acids need to be derivatized so that they can produce strong absorption in the ultraviolet region and be detected by the detector. In the amino acid analysis method developed by Welch, Amino Acids are derivatized before the column. Complete sample preparation can be achieved in as short as 30 min.
Ultisil Amino Acid HPLC columns are made from spherical, totally porous, and ultra-high purity (>99.999%) type B silica particles. Our proprietary surface modification before bonding generates a very smooth and uniform surface with less acidic surface silanol. Ultisil Amino Acid columns provide the best performance in peak shape, efficiency and resolution for the analysis of 18 amino acids. Complete sample preparation can be achieved in as short as 30 min.
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.
