Malvern Panalytical Zetasizer Ultra

Dynamic Light Scattering (DLS)




Dynamic Light Scattering (DLS) uses a 632.8 nm, 10 mW HeNe laser to determine particle size while dispersed in a solution. This instrument posses 3 detectors, a backscatter, 90 degree, and forward scatter detector. The laser light is directed into the sample and the light scattering is analyzed by one or more detectors and analyzed to give particles size information. This system can also perform particle concentration measurements and zeta potential measurements.

We also possess an auto-titration accessory which can titrate a sample and perform measurements at set points in the titration.
