Short Description: ALV DLS/SLS Compact Goniometer System for combined use in static and dynamic light scattering experiments equipped with a HeNe Laser (23mW; 633 nm). Angular range: 10° to 135° (dynamic) and 25° to 135° (static). Detection system: either a SO-SIPD dual photomultiplier operating in pseudo cross correlation mode or an Avalange Photodiode (APD). Typical temperature range: -5°C - 50°C.		Picture of the Equipment
Available Experiments/Techniques: Zimm-Plot (Mw, Rg, A2), determination of particle form factors (R, Polydispersity), determination of hydrodynamic radii (Rh).
