Dvb stationary phase
WebJordi DVB columns offer unsurpassed strength and durability as compared to conventional GPC columns, which typically contain silica-based or polystyrene-DVB (PS-DVB) stationary phases. A proprietary DVB chemistry provides a stationary phase that exhibits versatile solvent compatibility, high pressure durability (30,000psig), high temperature ... Websize PLRP-S stationary phases, a range of oligonucleotides, 25, 50, 75, and 100 bases, were prepared at a known concentration. These solutions were pumped through the different columns until saturation point was exceeded. It is a useful indication of the ability of a stationary phase to bind a molecule, and is therefore helpful in determining
