SEPLITE ® Weak Base Anion Exchange Resin The Weak Base Anion Exchange Resin  with primary, secondary, tertiary amine or mixed amine group as active functional groups show different strengths of alkalinity. Most weak Base Anion Exchange Resins with mixed amine group equiped a extremely high operating capacity with the ability to remove both strong and weak acids from solution. There are two kinds of weak base anion resin , Gel type and Macroporous type, which have acrylic backbone, styrene backbone or mixed backbone. Weak base anion exchange resins are more chemically stable and higher resistant to organic fouling than strong base anions. The weak base anion exchange resin is easier to regenerate than the strong base resin, and can be efficiently regenerated with a small amount of sodium hydroxide. Weak base ion learning exchange   resins are commonly used in pharmaceutical, food engineering, and chemical engineering, such as the removal of mineral acid, organic acids a

SEPLITE ® Weak Acid Cation Exchange Resin acidic ion exchange resin ? The words below would give a proper answer. The weak acid cation exchange resin is the type of ion learning exchange  resin with functional group of carboxylic acid group (-COOH) . They show weak acidity like acetic acid, having the ability to exchange with bases such as NaOH and weak acid salts such as NaHCO3. The weak acid cation exchange resins have two kinds of chemical structures, a methacrylic acid type and an acrylic acid type. This makes a difference for the ion exchange ability. The methacrylic acid type can be used at pH above 5, while the acrylic acid type can be used at pH above 4. Even though use is restricted, it is easier to regenerate than a strong acid cation exchange resin. W eakly acid cation exchange resin  are suitable in the fields of removal of water dealkalization, carbonate hardness, purification of antibiotics and amion acid. It is not used much for water processing because

SEPLITE ® Strong Base Anion Exchange Resin The strong base anion resin  is the type of ion exchange resin with functional group of quaternary ammonium, which is strongly alkaline and dissociates just like NaOH and KOH. In chemical structure, there are two types of strong base anion exchange resin  with different alkalinity strengths, Type Ⅰ with a trimethyl ammonium group, Type Ⅱ with a dimethylethanol ammonium group. Type Ⅰ shows a higher alkaline than Type Ⅱ. Compared with type 1 strong base anion, this resin is more suitable for applications needing good rinsing performance and excellent regeneration efficiency. The Strong Base Anion Exchange Resin shows an excellent physical and chemical stability, which is capable of exchanging the different anion under a wide range of pH. The I on L earning E xchange  is mainly used in water treatment, to produce high purity demineralized water, making use of the ability to adsorb anions strongly. Typical Applications For Str

SEPLITE ® Strong Acid Cation Exchange Resin The Strong Acid Cation Exchange S ac   Resin  is the type of ion exchange resin with functional group of sulfonic acid The Strong Acid Cation Exchange Resins have two types, the gel and the macroporous type. The macroporous strong acid cation exchange resin shows an excellent dynamic characteristics. The gel type has excellent properties for industrial water softening and demineralization application. It has standard crosslinkage, which is usually used in mixed bed; the higher crosslinkage resin shows a longer operating life, and used in regenerable mixed bed. The Strong Acid Cation I on L earning   Exchange  Resin shows an excellent physical and chemical stability, which operates at any pH(0-14), and are relatively stable to temperture, even in high temperatures of 100-120℃. The Strong Acid Cation Exchange Resin is applied in a wide variety of fields including water purification, water softening, waste water treatment, purif

S ieber A mide R esin 9-Fmoc-Aminoxanthen-3-yloxy-polystyrene resin A hyper acid-labile linker or the Fmoc SPPS of protected amides via mild 1% TFA cleavage. The ion learning exchange  can be readily reductively alkylated to provide a support suited to the synthesis of secondary carboxamides. This resin has also been employed to produce protected peptide fragments in wich the C-terminal carboxylic acid group is blocked as a hydroxymethylphenoxy-β-alaninamide ester.

Antibiotice   purification; Peptide antibiotic synthesis; Enzyme-catalyzed reaction; Chromatographic separation Modern biopharmaceutical technologies typically  of decolorization resin  use biological microbial fermentation processes, enzyme-catalyzed reactions, or biologically metabolites obtained by cell culture. Biosynthesis technology can produce many active substances, such as antibodies, antibiotics, etc., but the concentration of biologically active substances is very low, and some is easy to be inactivate, the content of impurities is very high, and many impurities and targets have similar physical and chemical properties, which result Separation and purification difficult. Sunresin's large pharmaceutical research and development department has proposed different solutions to various problems arising in the biopharmaceutical process through an in-depth understanding of the upstream and downstream industries of biopharmaceuticals. So far, many of our products have

Lanthanides The lanthanide series of chemical elements from periodic table in resin   comprises the fifteen metallic chemical elements withatomic numbers 57 through 71, from lanthanum through lutetium . These fifteen lanthanide elements, along with the chemically similar elements scandium and yttrium, are often collectively known as the rare earth elements  for ion learning exchange . Actinides The actinide series encompasses the 15 metallic chemical elements with atomic numbers  from 89 to 103, actinium through lawrencium.The actinide series derives its name from the first element  of periodic table resin  in the series, actinium.They all have very large atomic andionic radii and exhibit an unusually large range of physical properties. While actinium and the late actinides (from americium onwards) behave similarly to the lanthanides, the elements thorium through neptunium are much more similar to transition metals in their chemistry.

4-Hydroxymethyl-phenylacetamidomethyl resin PAM resin  has become the most widely used resin in Boc chemistry peptide synthesis. It has greater acid stability than Merrifield resin, making it suitable for synthesizing medium and large peptides, such as DNA binding polyamines, human matrix Gla protein(MGP), Kappa-casein. The first carboxylic acid of ion learning exchange   is attached to PAM resin using an activating agent such as DCC and DMAP. These conditions can lead to partial epimerization of the amino acids, so HOBt is normally added to reduce racemization.

SEPLITE ® Mixed Bed Ion Learning Exchange  Resin Mixed bed is typically cation and anion ion exchange resin all in one mixture. amberlite mb20 resin  is  mainly used in the water purification industry for polishing process water to achieve demineralized water quality, usually after a reverse osmosis system. The Mixed bed Resins are the typical resins with mixture of strong acid cation resins in H+ form and strong base anion resins in OH- form. The ratio of component resins is designed to provide high capacity depending on the application.Several mixed bed resins are available with indicator which facilitate the operation because of color change when exhaustion. The two resins are mixed to be used in one column for fully purification of water, to reduce the water conductivity. The mixed bed ion exchange process   is  usually used in the Electrical Discharge Machining plant for water demineralization. Typical Applications For Mixed Bed Ion Exchange Resins Water deion
