Analysis of Polystyrene Oligomers by Semi-micro GPC

Semi-micro GPC analysis has the advantage in cutting cost by reducing the consumption of mobile phase. Columns with smaller particle sizes and reduced column dimensions are ideal for rapid high performance analysis. The RI-4035 refractive index detector with small flow cell volume is optimized for high-speed data acquisition for use in semi-micro scale analysis, using columns with high performance packing material with smaller particles. This report shows polystyrene oligomer analysis, using a GPC column designed for high-performance analysis, resulting in a 30% solvent saving.
