The Anton Paar Litesizer™ 500 is an instrument for characterizing nano- and microparticles in dispersions and solutions. It determines particle size, zeta potential, and molecular mass by measuring dynamic light scattering (DLS), electrophoretic light scattering (ELS), and static light scattering (SLS). The Litesizer 500 can measure particles in the range of 0.3 nm and 10 µm.
The Malvern Zetasizer Nano ZS is a high performance two angle particle and molecular size analyzer for the enhanced detection of aggregates and measurement of small or dilute samples with a size range between 0.3 nm to 10 um using dynamic light scattering with ‘NIBS’ optics. The ZS also incorporates a zeta potential analyzer that uses electrophoretic light scattering for particles, molecules and surfaces, and a molecular weight analyzer using static light scattering.
