SEPLITE ® Weak Base Anion 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 exchange resins, 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 anion exchange resins are commonly used in pharmaceutical, food engineering, and chemical engineering, such as the removal of mineral acid, organic acids and other

SEPLITE ® S trong B ase A nion R esin The Strong Base Anion Exchange Resin (   SBA 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 exchanger  shows an excellent physical and chemical stability, which is capable of exchanging the different anion under a wide range of pH. The Strong Base Anion Exchange Resin is mainly used in water treatment, to produce high purity demineralized water, making use of the ability to adsorb anions strongly. Typical

Peptide Synthesis Resins Since Solid Phase Peptide Synthesis (we can also call it spps resins )  was first proposed by Robert Bruce Merrifield, the method of synthetic peptides became more popular than liquid phase peptide synthesis because of high efficiency. This method could assemble a peptide chain rapidly through successive reactions of amino acid derivatives on an insoluble support. The original peptide antibiotics are also biosynthesized and extracted from the culture of polymyxa or aeruginosa. Another synthetic method of peptides is chemical synthesis, which is divided into liquid phase chemical synthesis and solid phase chemical synthesis. The liquid phase method is mainly used for the synthesis of short peptides. The solid phase synthesis method can be used to prepare long-chain peptides, cyclic peptides, and complex. Peptide. The solid phase method is divided into a Boc method and an Fmoc method. It requires the solid phase synthesis of the carrier to achieve the gr

SEPLITE ® Mixed Bed Ion Exchange Resin Mixed bed is typically cation and anion ion exchange resin all in one mixture. A mberlite 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 resin for water treatment   is usually used in the Electrical Discharge Machining plant for water demineralization. Typical Applications For Mixed Bed Ion Exchange Resins Wa

Are you looking for ion exchange resin buy ? SEPLITE® Ion Exchange Resins Ion exchange is a powerful chemical technology, through a reversible chemical reaction, where dissolved ions are removed from solution and replaced with other ions of the same or similar electrical charge. Ion exchange resin facilitates ion exchange reactions. The resin itself is composed of organic polymers that forms a network of hydrocarbons, and ion exchange sites, called”functional group” throughout the matrix. The ion exchange sites attract ions of an opposing charge, which give the ion exchange resin its separation capabilities. Ion exchange resins are classified into cation exchange resins and anion exchange resins, as well as mixed bed ion exchange resins. The cation exchange resin can be exchanged with a cation, and the anion exchange resin can be exchanged with an anion. The mixed bed ion exchange resin is a physical mixture of a positive resin and an anion resin, and at the same time remo

SEPLITE ® Indicator Mixed Bes Ion Exchange Resin Indicator Mixed Bed Ion Exchange Resin is typically cation and anion ion exchange resin all in one mixture with color indicator Mixed bed ion exchange resin is a kind of polishing resin for deionization, which lead a high-resistance pure water in a long service life. In order to ensure the water quality, Mixed Bed ion exchange Resin is required to replace timely when exhausted. Indicator Mixed Bed ion exchange Resin could indicate the working state of inert resin   anytime. The indicator makes the resin change color when mixed bed ion exchange resin exhausted, that you needn’t to prepare the professional test equipment and study the test method. Just as the Mixed bed ion exchange Resins, Indicator Mixed Bed ion exchange Resin is also the typical resins with mixture of strong base anion exchange resins in OH- form and strong acid cation exchange resins in H+ form. Mostly, Indicator is bonding to strong base anion exchan

SEPLITE ® Chelating Resin SEPLITE® chelating resin  is ion exchange chelating resins for metals removal, recovery and enrichment. Chelating resins are a class of ion exchange resins with reactive functional groups that chelate to metal ions. They have the same bead form and polymer matrix as usual ion exchange resin, and the variation in chelating resins arises from the nature of chelating agents linked into a polymer backbone. SEPLITE ® Chelating resins contain a wide range of special functional groups that gives them superior selectivity for specific target metals, Such as SEPLITE®LSC710, which is the iminodiacetic acid bonded in a styrene-divinylbenzene matrix. Other functional groups bound to chelating resins are aminophosphonic acid, thiourea, 2-picolylamine and so on. Chelating resins are almost always used to bind cations, which are found in a big range of metals removal, recovery and enrichment in a dilute solution. Chelating ion exchange resin  for brine decal
