Analysis of Virus Particles by Dynamic Light Scattering
15th July 2020
The latest informative newsletter from our partner Brookhaven Instruments focuses upon applications of the BI-MwA. The BI-MwA is a unique GPC/SEC detector designed to be used in both batch and flow modes. Key applications of the product include collecting light scattering data at different polymer concentrations as well as determining the molecular weight, radius of gyration (Rg), and second virial coefficient of polymer samples thereby giving information on both size and shape of the polymer molecule. Beneficially the method is absolute, requiring no calibration. Read More
