Time：2020-06-02 06:44Click：108
●The bonded stationary phase is a kind of mixed strong cation exchange filler, which is based on silica gel with high purity and good mechanical stability and prepared by using high purity bonding reagent. It has a mixed chemical structure of sulfonic group and phenyl functional group.●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 11.0%. 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 density of the packed bed is uniform and stable by using the unique homogenate loading technology, so it can ensure the high column efficiency of Zui.
●Target SCX column is a mixed mode of strong cation exchange phase and hydrophobic phase, which not only provides efficient and highly selective separation for cation / alkaline and nitrogen-containing compounds, but also has suitable retention for a variety of weak cations and neutral organic compounds.
● pH stability: 2-8.5 typical application fields include the separation of organic bases such as basic amino acids, aniline, salt drugs, inorganic cations, nucleosides, etc.
