ZETASIZER PRO AND ZETASIZER ULTRA ADVANCE WITH CONFIDENCE

LIGHT SCATTERING ANALYSIS FOR YOU Light scattering is a fundamental analytical technique for the characterization of particulate materials, and is most commonly applied to colloidal systems, nanoparticles and macromolecules in solution or dispersion, to determine particle size, molecular weight, or electrophoretic mobility. Different methods of light scattering analysis provide a range of useful information about your samples: Dynamic Light Scattering (DLS) measures the size and size distribution of molecules and particles Electrophoretic Light Scattering (ELS) measures the electrophoretic mobility...

BIOSCIENCE AND BIOPHARMACEUTICALS Temperature or pH changes, agitation, shear, and time all impact the stability of biological molecules, causing denaturation and aggregation, loss of function, and possibly undesirable immune response, in the case of biopharmaceuticals. The Zetasizer ® range provides rapid purity and stability screening, and assists with formulation development so that processes and products can be optimized and de-risked PAINTS, INKS AND COATINGS Paint, ink and coating formulations must be stable to keep them in an optimum state over time without change or aggregation. Particle...

WHY USE LIGHT SCATTERING? There are various types of light scattering, each designed to provide useful and actionable physicochemical information on the sample being analyzed. The Zetasizer Pro and Zetasizer Ultra both offer two types of light scattering technology as standard: dynamic light scattering (DLS) and electrophoretic light scattering (ELS). The frequency and intensity of the scattered light can be measured to determine the size and charge of materials. This information is commonly used to shorten development time for, and improve the stability of, colloidal (including protein) and...

The instruments' new form, incorporating...

A FOUNDATION OF EXCELLENCE Pioneer technologists at the heart of Malvern Panalytical were pivotal to the commercial development of light scattering methods for particle size analysis. Scientists at the Royal Signals and Radar Establishment (RSRE, Malvern, UK), applied digital correlation techniques to analyze the scattering from particles undergoing Brownian motion. This led to the development in late 1971 of the world’s first commercial correlator, and to Malvern Instruments and RSRE being jointly awarded the prestigious MacRobert engineering award for Outstanding Technical Innovation on the...
