Multiple Laser Light Scattering Goniometer
25th August 2020
Testa Analytical Solutions e.K announce the launch of an upgrade kit for its BI-200SM light scattering goniometer system providing access to multiple laser Static Light Scattering (SLS) and Dynamic Light Scattering (DLS) techniques.
Traditionally, selection of the most appropriate wavelength for SLS or DLS applications has necessitated replacement of one laser with a different one, a time-consuming operation requiring precision re-alignment work. Alternatively, users could elect to employ a single, very costly multi-wavelength Ar-Ion laser in their light scattering goniometer system.
