报告摘要：The LSSpectrometer is a modern goniomter-based static & dynamic light scatteringinstrument for advanced colloid and polymer characterization. It providesmeasurement of key physical polymer characteristics including molecular weight,second virial coefficient and radius of gyration. Characterization ofnon-ergodic systems such as high concentration or cross-linked polymers is alsopossible. Variable-angle dynamic light scattering and a free-solution approach enablesmeasurement of complex size distributions even for very large polymers as wellas shape characterization and rotational dynamics. By leveraging a patented'Modulated 3D Cross Correlation' technique for multiple light scatteringsuppression, the platform provides accurate and reliable measurements ofdiffusion coefficients at any concentration.
