AN ADVANCED MULTI-ANGLE LIGHT SCATTERING DETECTOR. IT MEASURES THE INTENSITY OF SCATTERING AT EACH ANGLE SIMULTANEOUSLY WHICH IN CONJUNCTION WITH A CONCENTRATION DETECTOR IS USED TO CALCULATE ABSOLUTE MOLECULAR WEIGHT OF PROTEINS, SYNTHETIC AND NATURAL POLYMERS, AND ALSO MOLECULAR SIZE EXPRESSED AS THE RADIUS OF GYRATION, Rg. THE PRODUCT USES A RED LASER TO ILLUMINATE THE SAMPLE AND THEN COLLECTS LIGHT SCATTERED BY THE SAMPLE. OTHER FEATURES ARE A VERTICAL FLOW CELL WITH ADVANCED RADIAL OPTICS FOR IMPROVED PERFORMANCE. IT ALSO FEATURES A SINGLE FLOW CELL COMPATIBLE WITH ALL SOLVENT REFRACTIVE INDICES. THE PRODUCT HAS THE FACILITY OF USING A UV OR RI DETECTOR. AS WELL AS USING LIGHT SCATTERING THE PRODUCT IS COMPATIBLE WITH SIZE-EXCLUSION CHROMATOGRAPHY (SEC)
