Malvern Panalytical Zetasizer
: Multi-Angle Dynamic Light Scattering (MADLS) for absolute confidence in particle and molecular size distribution analysis
: Dynamic Light Scattering (DLS) measures particle and molecule size, from below 1 nm to 10 µm
: Non-Invasive Back Scatter (NIBS) optics for versatile, high sensitivity, particle and molecular size measurements
