Molecular Weight Analyzer Uses Static Light Scattering
The BI-MwA Molecular Weight Analyzer uses static light scattering to measure molecular weight distribution in dilute polymer solutions. The instrument has a 660-nm diode laser and uses seven different angles to determine the intensity of scattered light as a function of angle and polymer concentration. It can be used in batch or flow mode, as a chromatography detector, or for measuring the rate of polymerization using time-dependent static light scattering. The flow path is vertical, not horizontal, avoiding trapped bubbles. There are no sharp corners inside the cell, only conical shapes. Previous solutions are more easily flushed.
