Dynamic light scattering.
The Model 802 dynamic light scattering (DLS) instrument features the company's dual attenuation technology (DAT), a technique that controls the level of light entering the sample, as well as controlling scattered light going to the detector. In this way, researchers are able to work at the optimum conditions for the laser and detector, irrespective of sample type. In combination with OmniSize 3.0 software, the Model 802 DLS with DAT is able to automatically adjust the instrument to its optimum setting, sample by sample, according to the company.
