Target-SAX
● the bonded stationary phase is based on silica gel with high purity and good mechanical stability, which has a mixed chemical structure of quaternary ammonium and phenyl functional groups by bonding quaternary ammonium strong anion exchange group on silica gel with high purity bonding reagent.●The unique innovative design of the bonding phase can maximize the coverage of single functional group, and the carbon content can be as high as 17.0%. Because of its maximum surface coverage, it has excellent stability. The filler is a uniform spherical particle with a pore diameter of 110 Å and a specific surface area of 300m2 / g.
● by strictly controlling the chemical reaction conditions of bonding phase synthesis, reliable reproducibility between columns can be ensured. The Sax column bed density obtained by using the unique homogenate loading technology is uniform and stable, so it can ensure a high column efficiency of .
●Target-SAXcolumn is a mixed mode of strong anion exchange phase and hydrophobic phase, which can provide efficient and highly selective separation for various organic compounds such as aromatic or aliphatic carboxylic acids and sulfonic acids. Typical application fields include the separation of insecticides, herbicides, drugs, inorganic anions and biological samples (such as nucleotides and sugars). The column can use a variety of mobile phases, including organic solvent, water and organic solvent mixture (such as methanol and acetonitrile), buffer (such as phosphate), etc.
