Name: Amphoteric Ion-Exchange Resin DIAION? series
Description:DIAIONTM AMP03 is an amphoteric ion-exchange resin with a quaternary ammonium group and carboxy group incorporated into the crosslinked polystyrene backbone. Thanks to uniform 260 µm beads size, AMP03 realizes sharp elution peak in the separation of electrolytes from non-electrolytes, between electrolytes(sodium chloride and sodium sulfate), etc.
Name: Low-odor and Low-leachable Anion Exchange Resins DIAION? serie
Description:The low-odor, low-leachable anion exchange resin reduces the release of total organic carbon(TOC) and amines to prevent offensive odors.;Packed column or Batch processing
Name: Weakly Basic Anion Exchange Resins DIAION? series
Description:The weakly basic anion exchange resins use either a polystyrene or polyacrylic ester frame and a primary-ternary amino group as the functional group. Although the anion of a salt like NaCl or Na2SO4 cannot be exchanged, the exchange of an anion of a mineral acid such as HCl and H2SO4, or the salt of a weak base like NH44Cl can be carried out.
Name: Storngly Basic Anion Exchange Resins DIAION? series
Description:An amino functional group is incorporated into the anion exchange resin enabling the exchange of anions like the Cl- ion and the SO4-- ion. Strongly basic anion exchange resins and weakly basic anion exchange resins can be defined according to the basic strength of the amino functional group. The ion exchange resin that has a quaternary ammonium group is strongly alkaline and dissociates just like NaOH and KOH. Therefore it is called a strongly basic anion exchange resin.
Name: Weakly Acidic Cation Exchange Resins DIAION? series
Description:The weakly acidic cation exchange resins have the carboxylic acid group(-COOH) as the exchange group. There are two kinds --- a methacrylic acid type and an acrylic acid type. The acrylic acid weakly acidic cation exchange resin is used for processing water with high carbonate hardness. The methacrylic acid type is used for purification of antibiotics and amino acids.
Name: Strongly Acidic Cation Exchange Resins DIAION? sereies
Description:The strongly acidic cation exchange resins are bead-like products which have a sulfonic acid group in the cross-linked styrene frame. They can be used across the full pH range(0-14), and are relatively stable to temperature, even withstanding high temperatures of 100-120℃. They are used in a wide variety of fields including water purification, water softening, wastewater treatment, purification of pharmaceuticals and food, and catalysis.
