Reverse Phase Polymer Chromatography
EPRUI Biotech Co. Ltd. offers a new generation of reversed phase polymer HPLC packing material. Our polymer chromatography column packing material is made of highly crosslinked monodisperse polymer resins including highly crosslinked polystyrene divinylbenzen, polymethyl methacrylate, copolymers of PS/DVB and PMMA. With precise control of particle size, particle size [...]
Silica Gel Chromatography
Silica gel chromatography packing is made of monodisperse porous silica microspheres with highly uniform particle size, perfect spherical morphology and optimized pore structure. Our silica gel chromatography media meets the requirements of high performance liquid chromatography (HPLC) analysis in the laboratory and preparative separations in industry scale. The monodisperse [...]
Protein A Affinity Chromatography
Protein A affinity chromatography medium by EPRUI is based on the monodisperse porous poly (methyl methacrylate) (PMMA) microspheres as the matrix, and genetically modified protein A as the ligand, which ensures its high affinity binding of monoclonal antibodies and Fc fragment containing recombinant proteins (macromolecules). Our protein A chromatography [...]
SPE HLB Sorbents
SPE-HLB sorbents are produced with a special polymerization technique. It is corrresponding to Water Oasis HLB or Phenomenex Strata X. They are reverse phase sorbents wettable by water with balanced hydrophilicity and hydrophobicity capable of satisfying most solid phase extrction needs. Monodisperse microspheres in SPE-HLB sorbents are made with outstanding [...]
Anion Exchange Chromatography
SPE-SAX and SPE-WAX are used for the isolation and purification of acidic compounds in basic or neutral medium. Based on a mixed mode of anion ion exchange and hydrophobicity interaction with functional quaternary / tertiary amino groups, SPE-SAX and SPE-WAX can quickly and steadily recover acidic compounds from the [...]
Cation Exchange Chromatography
SPE-HLB sorbents are produced with a special polymerization technique. It is corrresponding to Water Oasis HLB or Phenomenex Strata X. They are reverse phase sorbents wettable by water with balanced hydrophilicity and hydrophobicity capable of satisfying most solid phase extrction needs. Monodisperse microspheres in SPE-HLB sorbents are made with outstanding [...]
Sugar Analysis HPLC Phases
EPRUI Biotech develops a series of size controllable HPLC packing which is especially for the analysis and separation of carbohydrates including fruit juice containing organic acid, sugar alcohol, simple sugar, polysaccharide and so on. It is a kind of cationic exchange chromatography media which is prepared by sulfonating PS/DVB [...]
