Super-dynamic Light Scattering Spectrophotometer DLS/SLS series
features
Measures particle size and particle-size distribution based on the dynamic light-scattering method. Measures absolute molecular weight, radius of gyration, and the second virial coefficient based on the static light-scattering method.
He-Ne laser, Ar laser, double laser (He-Ne, Ar) models are available.
Adopts a liquid-immersion optical system, supporting high-precision measurement for extremely weak scattering of nano-order particles.
Supports multimode analysis of concentrated polymer solutions, using a correlator providing up to 4,096 channels.
Supports gel-state analysis in combination with the optional gel-rotation cell.
