Dynamic Light Scattering (DLS) for Relative Molecular Mass Determination
Dynamic Light Scattering (DLS) is a rapid and effective method for determining the relative molecular weight of polymers by analyzing their hydrodynamic radius. This technique calculates the molecular weight based on the average static light diffraction measured in a concentration series of an unknown sample. To perform polymer molecular weight analysis, specialized glass and quartz cuvettes are used, with toluene often employed as a standard sample.
Key Features of our DLS Device
Our Zetasizer Nano ZSP System is equipped with a 633 nm laser and utilizes glass and quartz cuvettes for accurate measurement of polymer molecular mass. It is capable of determining the molecular weight of polymers within the range of 980 daltons to 20 megadaltons.
