The Zetasizer Nano ZS90 is the perfect lower cost solution when the ultimate in sizing sensitivity is not necessary, or where identical results to a legacy system with 90 degree scattering optics is required. The ZSP 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.
The 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, and samples at very low or high concentration using dynamic light scattering with ‘NIBS’ optics. The Zetasizer Nano Z is the perfect system for measuring zeta potential and electrophoretic mobility of colloids and nanoparticles, when the measurement of size or molecular weight is not required. The Malvern Instruments Zen 3600 Zetasizer is capable of measuring the size, molecular weight, and zeta potential measurement of dispersed particles and. The Zetasizer Nano S90 is the perfect lower cost solution when the ultimate in sizing sensitivity is not necessary, or where identical results to a legacy system with 90 degree scattering optics are required. It has the same sizing capability as the top of the range The addition of Constant Current Mode for measuring electrophoretic mobility and zeta potential in high conductivity media reduces errors that can be associated with electrode polarization at higher ion concentrations.The Zetasizer Nano S is the system of choice where the highest sensitivity and widest size range is required. The information provided by these measurements is an excellent indicator of sample stability and/or propensity to aggregate. The capillary cells enable measurements in extremely low volumes, without direct sample-electrode contact using the Malvern's patented diffusion barrier method and avoids sample cross-contamination. This technique measures the diffusion of particles moving under Brownian motion, and converts this to size and a size distribution using the Stokes-Einstein. For zeta potential measurements the instrument requires affordable disposable folded capillary cells. The Zetasizer Nano ZS incorporates three techniques in a single compact unit: Dynamic Light Scattering (DLS) is used to measure particle and molecule size. The Zetasizer Ultra also provides the highest sensitivity zeta potential and electrophoretic mobility measurements using M3-PALS technology. This is a unique capability of the Zetasizer Ultra which can even be applied to samples such as viruses and VLPs, which were previously very challenging to measure. The Malvern Zetasizer Nano ZSP uses light scattering to evaluate nanoparticle sizes from 0.3 nm to 10 um in diameter. The measurement of particle concentration is calibration-free, suitable for a wide range of materials, requires no or little dilution, and is quick to use – all of which make it ideal as a screening technique.
NIBS provides the versatility and sensitivity to measure over a wide concentration range, while MADLS permits a higher resolution view into your sample’s size distribution for those critical measurements.Īn extension to MADLS affords the ability to analyze particle concentration of monodisperse samples below 500 nm. The Zetasizer Ultra is the world’s most capable combined DLS and ELS system, incorporating Non-Invasive Back Scatter (NIBS®) and, uniquely, Multi-Angle Dynamic Light Scattering (MADLS) technology for the measurement of particle and molecular size.
