High-Resolution Columns Exhibit Wide Pore Size Distribution

Designed for high-resolution organic GPC, PlusPore GPC column technology uses a polymerization process to produce particles that exhibit a specific, controlled pore structure for optimum GPC performance. For high-resolution polymer analysis, the product line exhibits a wide pore size distribution with near linear calibration curves covering an extended molecular weight range. These 'multipore' structures have increased pore volume compared to regular PS/DVB packing materials. The columns feature notable chemical and physical stability and permit transfer across the range of organic solvents with little change in the shape of the calibration curve or column efficiency. This multipore column technology eliminates the need for individual pore size packings, resulting in accuracy without any artefacts in the shape of the molecular weight distribution. The PlusPore series comprises PolyPore columns for general polymer analysis, ResiPore columns for resin and condensation polymer analysis, MesoPore columns for prepolymer and low MW resin analysis, and OligoPore columns for oligomeric sample analysis.
