AN INSTRUMENT USED FOR THE MEASUREMENT OF SIZE, MOLECULAR WEIGHT, FOR PROTEIN ANALYSIS WHICH USES GEL PERMEATION CHROMATOGRAPHY (GPC). IT COMBINES MEASUREMENTS OF MOLECULAR WEIGHT BY STATIC LIGHT SCATTERING (SLS) WITH MEASUREMENTS OF MOLECULAR SIZE (Rh) BY DYNAMIC LIGHT SCATTERING (DLS). IT CAN PERFORM BOTH OF THESE MEASUREMENTS IN BATCH AND GPC/SEC FLOW MODES. THE DETECTOR IS OPTIMIZED FOR THE MEASUREMENT OF SMALLER MOLECULES THAT SCATTER LESS LIGHT, MAKING IT IDEAL FOR PROTEIN MEASUREMENTS. .
