产品说明

20 micron particle size is used for high resolution and small scale preparative to semi-preparative separation of biomolecules. POROS™ High Performance Chromatography™ Media and Pre-Packed Columns • Chemical stability: Allows aggressive cleaning and sanitization • Polystyrenedivinylbenzene particles: Yield a robust, easily packable matrix You can replace many sample preparation steps with high speed High Performance Chromatography technology. For instance, dialysis of large volumes of material can be replaced by high flow rate processing of the dilute sample. Elution in a small volume of new buffer accomplishes both buffer exchange and concentration. Create novel assays for more efficient analysis In contrast to conventional chromatography media, POROS™ High Performance Chromatography™ resins particles, are engineered to have two discreet classes of pores. Large "throughpores" allow convection flow to occur through the particles themselves, quickly carrying sample molecules to short "diffusive" pores inside. By reducing the distance over which diffusion needs to occur, the time required for sample molecules to interact with interior binding sites is also reduced. Diffusion is no longer limiting and flow rates can be dramatically increased - without compromising resolution or capacity. Separations can be achieved at 1,000 to 5,000 cm⁄hr compared to 50 to 360 cm⁄hr for conventional media.
