WebA MALS detector is a type of light scattering measurement system, which allows for the detection of light scattered by components of a solution into multiple distinct angles. Many times MALS detectors are coupled with ... Wyatt Technology Corporation Type: Multi-angle Light Scattering (MALS) and optional dynamic light scattering ... Webtriple detection–UV, differential refractive index (dRI), and multi-angle light scattering (MALS)–has been developed to measure the following three important AAV quality attributes (QAs): 1) Total number of viral capsid particles; 2) Relative capsid content (e.g., ratio of empty and full capsids); and 3) Percentage of monomer or aggregates.
Web1 mrt. 2024 · The MALS detector, connected to an SEC chromatographic system, directly measures the molar mass and the root‐mean‐square (RMS) radius (also called radius of gyration, Rg) of polymer molecules eluting from SEC columns. Web10 apr. 2015 · The procedure is comparable to the one using an RI detector. The first step is to calibrate the instrument (determine the detector constant), which is performed using NaCl or KCl solutions. Afterwards the sample dn/dc can be measured by manually injecting five or more concentrations ranging from 0.1 mg/mL to 10 mg/mL.
