EPRUI Biotech Co. Ltd. supplies various polymer HPLC packing materials including Polystyrene divinylbenzene or PS-DVB reverse phase chromatography(RPC) packing material, ion exchange chromatography column packing material, Solid phase extraction(SPE) chromatography packings, sulfonated PS/DVB resins for separation and analysis of sugar.
The polymer HPLC column packing materials from EPRUI is made of monodisperse microspheres with narrow particle size distribution such as high crosslinked PS/DVB microbeads, monodisperse PMMA microspheres and so on.
Polystyrene divinylbenzene or PS-DVB microspheres are robust polymer material used as the base framework for most EPRUI’s polymer HPLC packing materials. The high degree of cross-linking with divinylbenzene makes the polymer bead extremely durable for high pressure applications.
Besides, we can also supply size controllable magnetic beads which are easy to disperse and has good super paramagnetic effect and biocompatibility. By linking different functional groups such as –NH2,-OH,-COOH, epoxy groups, etc, magnetic beads can be widely used in the industries of clinical diagnosis, biological imaging, target drug delivery, cell screening, immunoassay, and especially protein, antibody, DNA/RNA/ nucleic acid purification.
