Malvern Instruments is the worlds leading supplier of particle sizing instrumentation. Long established as a world leader in laboratory-based, on-line and at-line particle analysis, Malvern’s solutions now include the following technologies: laser diffraction, image analysis, zeta potential, static and dynamic light scattering and strain and stress controlled rheometry. These technologies support measurement of the following physical properties: particle size distribution, zeta potential, particle shape, molecular weight and rheological properties.
The technique of dynamic light scattering (DLS) is ideally suited for the determination of the size of particles in the nanometer size range. The Malvern Zetasizer Nano S uses patented optics that provides exceptional levels of sensitivity and allows the determination of the size of samples that contain very small particles and/or particles that are present at very low concentrations. In addition, the backscatter optics allows for the measurement of samples at much higher concentrations than is possible using conventional DLS instruments using a 90° detection angle.
The new Zetasizer Nano series can measure a combination of three of the most important parameters for the colloid and polymer chemist, particle size, zeta potential and molecular weight.
The new technology incorporated in these systems provides unequalled sensitivity and versatility. The patented NIBS optics incorporated into the Nano Z and Nano ZS also allows measurements of samples with little or no dilution.
- Particle size - NIBS technology enables measurements of particles and molecules from 0.6nm to 6 microns.
- Zeta potential - M3-PALS technology enables accurate measurements of zeta potential in aqueous and non-aqueous dispersions.
- Molecular weight - An avalanche-photodiode detector and fibre detection optics give the sensitivity and stability required for absolute molecular weight measurement.
The Zetasizer Nano ZS is the pinnacle of the Malvern Zetasizer Nano series and can measure all three parameters with no performance compromises.
All systems are compatible with the MPT-2 autotitrator to enable trend measurements and sample preparation to be automated.
The Zetasizer Nano ZS provides comprehensive particle size and zeta potential measurement capability. For a complete technical description of Nano ZS features click here.
