1 We offer an amazing selection of Polymer Resins from Mitsubishi (PSDVB). For over 60 years Mitsubishi has been manufacturing ion exchange resins with excellent performance, superior physical and chemical properties, and lot-to-lot reproducibility for lab and industrial separation, extraction and purification applications. Polymer resins are a series of products based on ion-exchange resin manufacturing technology and are specifically designed as a solid extractant. Synthetic adsorbents have large surface areas and fine pore structures inside the particle similar to activated carbon. Because of this characteristic, these resins can effectively adsorb organic compounds from aqueous solutions. Polymer resin adsorbents are stable in either acidic or alkaline solutions as well as organic solvents. These resins can also be easily regenerated for repeat use, increasing product life. Extraction processes with synthetic adsorbents reduce solvent usage and provide safer operations compared to conventional solvent extraction techniques. These resins are ph stable from 1-14, available from 10 μm to 1000 μm particle sizes, have a wide array of pore sizes, and a long lifetime. Package sizes are available from 10 g to 200 L.

3 - Ion Exchange, Purification Synthetic Adsorbents Aromatic Type: Diaion - HP20, HP20SS, SP20SS, Sepabeads - SP825 Food Grade Aromatic Type: Sepabeads - SP70, SP700, SP710 Modified Aromatic Type: Sepabeads - SP207, SP207SS Methacrylic Type: Diaion - HP2MG, SP2MGS HP20 synthetic adsorbent resin is a macroporous styrenic polymeric bead type resin designed for adsorption/desorption process scale applications. Its matrix provides an aromatic non-polar surface with excellent selectivity for hydrophobic areas of molecules, including biomolecules like antibiotics via low energy Van der Waal s interactions. It is remarkable for its wide pore polymeric structure which provides excellent broad spectrum adsorption characteristics. HP20SS and SP20SS are smaller size versions of HP20. The wide pore polymer matrix provides excellent kinetics and capacity for small biomolecules of both preparative and process scale. They offer a nice balance of pressure flow characteristics and true chromatographic fractionation and have also been successfully applied in simulated moving bed (SMB) applications for a variety of small biomolecules. They often compete with bonded silica supports for preparative and industrial applications offering a longer lifetime. The Sepabeads SP825 resin provides a smaller more uniform pore size distribution and higher surface area as compared to Diaion HP20. The increase in surface area is approximately two times that of traditional adsorbents, and nearly matches the surface area of activated carbon. In many applications, this means twice the working capacity for the same volume of resin. They are recommended for industrial chemical process applications, bio/pharmaceutical applications such as desalting and extraction, and waste treatment. SP70, SP700, and SP710 are premium grade resins designed for the debittering of juices and related food products. These high surface area resins offer excellent kinetics and high capacity for naringin (and other bittering agents). They meet the compositional requirements for Secondary Direct Food Additives (21 CFR Section ). SP70 and S710 are provided pre-conditioned to meet the extractive requirements as of the date of manufacture. SP207 resin is a macroporous chemically modified broated styrenic polymeric type resin. The broation of the aromatic ring provides increased hydrophobicity, and consequently, increased selectivity for hydrophobic molecules versus conventional styrene/dvb synthetic adsorbents like Diaion HP20 resin. In addition, the broation increases the resin density which allows for settling in fermentation broths, and for usage in upflow fluidized beds. SP207SS is a small size version of modified aromatic type Sepabeads SP207. SP207SS is used for applied to reversed phase chromatography. The broated polymeric matrix provides unique selectivity, full ph operating range and long operating life versus conventional bonded silica packing materials used in preparative and industrial applications. HP2MG is a macroporous methacrylate polymeric resin. It has no aromatic character. HP2MG grades have different selectivity than the classic Diaion HP20. It is recommended for broad spectrum adsorption and desorption of small and large molecules, long chain aliphatic molecules, decolorization and desalting applications, and should be evaluated as an alternate resin matrix to the styrenic based adsorbents. SP2MGS is a small and uniform particle size version of the methacrylate type Diaion HP2MG. SP2MGS gives higher dynamic capacity than HP2MG and shows strong retention and unique selectivity in normal phase chromatography. 42

In addition, they are also able to adsorb those with carboxyl groups, because under the weakly acid ph conditions in which antibiotics are stable, the carboxyl group is hardly dissociated. Moreover, their adsorption is usually strongest under weakly acid conditions and, therefore these adsorbents find wide application. The figure to the right shows the elution behavior of cephalosporin C. While operating conditions will not be exactly identical, there are many cases where a substance which can be separated by C18 Silica Gel may also be separated by the use of a synthetic adsorbent, such as Diaion HP20 in this case.

7 Strong Acidic Cation Exchange Resins Gel Type: Diaion SK1B, UBK10 Porous Type: Diaion PK228, RCP160M Strong Acidic Cation Exchange Resins are cross-linked polystyrene resins having sulfonic acid groups. Among the Diaion Product line, there are SK grades of gel type, PK grades of porous type, RCP160M of highly porous type. The standard shipping is sodium salt form. In some cases, the hydrogen form is available for catalysis applications such as esterification, alkylation, hydrolysis, hydration, etc. SK1B in Na+ and H+ form resin is our flagship premium grade, gel-type, strong acid cation resin. It has excellent properties for industrial applications and is recommended for industrial scale softening and de-eralization applications. Featuring standard crosslinkage as is used in situations where the raw water contains oxidizing substances. The PK resin grades are based on a porous styrene DVB polymer matrix. Their porous structure provides excellent durability against osmotic shock by swelling and shrinkage. PK228 is recommended for condensate de-eralization (L grade is recommended for best pressure flow performance). PK grades area also recommended for special applications such as de-ashing, de-colorization, and as a catalyst (as they have higher reaction rate in organic solvents than gel type resins). Unlike other ion-exchange resins, the UBK ion-exchange resin featuring good uniformity in particle size, reducing the reagent costs and spent waste waters useful where high purity water is needed for manufacturing processes. UBK ion-exchange resins are also used in many other fields because they have few large particles which can be easily broken by shrinkage and swelling. Diaion RCP160M is based on a macroporous crosslinked polystyrene matrix with sulfonic acid functional groups. This matrix is more open and porous than conventional grade resin with increased polymer surface available for intimate contact with solutes. In catalysis, the reaction rates are faster with RCP160M than standard grade resins, resulting in a higher degree of conversion during catalytic applications.

Among the Diaion product line, there are SA-grades of gel type, PA-grades of porous type, and HPA-grades of highly porous-type. The standard shipping is Cl- form (in some cases OH- form is available). Type I resins have trimethyl ammonium groups which impart higher basicity. In the co-current regeneration mode, the treated water will have the lowest silica leakage. Type I resins also have higher chemical stability and can be applied at higher temperature than Type II or acrylic based resins. SA10A is a Type I resin with standard crosslinkage. Porous-type ion exchange resins of a porous polymer matrix have good resistance against swelling and shrinking, though their exchange capacity is lower than gel-type ion exchange resins of the same degree of crosslinkage. These are effective when highly purified effluents are needed, e.g. removal of silica to very low concentration. They are suitable for treatments of waste waters with organic compounds.

12 Ultrapure Mixed Bed Resins Gel Type: Diaion SMT100 L, SMT200 L Mitsubishi Chemical offers several grades of mixed resins for non-regenerable mixed bed ion exchange applications. All mixed resins are typically offered in a 1:1 stoichiometric ratio (1 equivalence of cation equilibrium capacity to 1 equivalence of anion equilibrium capacity). SMT100L and SMT200L are manufactured to very stringent performance specifications, and prepared from component resins with the highest degree of conversion and considerations of purity. They will also provide exceptional performance relative to electrical resistivity and TOC leakage. In fact, rinsing to 18 egaohm resistivity is nearly instantaneous, and clearly superior to conventional mixed bed resins. The performance for TOC meets or exceeds all conventional mixed bed resins. The TOC rinse down performance is maintained over 12 months of storage. Diaion SMT200L offers remarkable performance relative to metals leakage. The cation component, SKT20L, has been prepared with low levels of metals in the resin phase (500 ppb). This improvement allows ppt metals leakage in the product water quality (actual performance is <0.1 ppt for 13 metals within 4 hours of rinse). These are mixed bed resins: 1 equivalent of cation exchanger to 1 equivalent of anion exchanger. This mixed bed is used for the production of ultrapure water for use in the semiconductor industry as well as in the production of high purity chemicals. The SMT200L has a higher purity than SMT100L as the ash content is reduced several folds within the resin matrix.

CR11 captures metal ions by chelation with its iodiacetate functionality. CR11 has a higher selectivity than strong and weak acid cation exchange resins for divalent ions, especially transitional metal elements such as copper, iron, etc. CR11 can capture metal ions at much lower ph than strong and weak acid resins. As CR11 has higher selectivity for divalent metal ions than monovalents, it can be used for such selective separation. CR20 is a special chelating resin with polyae functionality. CR20 captures metal ions by chelation with its polyae functionality with its high porous styrene-dvb matrix. CR20 has a high selectivity to heavy metal ions. It does not adsorb alkali metal and alkali earth metal ions, and therefore, it can be used for heavy metal recovery from highly concentrated alkali earth solutions.
