Malvern Panalytical – particle analyzer – Zetasizer Ultra

Technical Specifications

Key Features

ZETASIZER Ultra

• Multi-Angle Dynamic Light Scattering (MADLS) for high resolution angle-independent size measurements offers greater insight into the size distribution of your sample
• Disposable capillary sizing cell provides the ultimate in non-destructive, low volume (down to 3 μL) analysis, with an upper size range that extends to 10 μm
• Simple, calibration-free measurement of particle concentration in homogeneous sample types, covering a wide range of materials
• Electrophoretic Light Scattering (ELS) measures the zeta potential of particles and molecules, indicating sample stability and/or propensity to aggregate
• Sample-centric ZS Xplorer software enables flexible, guided use, and the capability to build complex methods with ease
• Optical filter wheel offers a fluorescence filter and both vertical and horizontal polarizers for analytical flexibility
• NIBS (Non-Invasive Back-Scatter) technology maximizes the dynamic range, providing the highest sensitivity for even the most concentrated samples
• The deep-learning empowered Data Quality System assists users in understanding which of their size data might be poor, and why. This intelligent neural network system also suggests how to improve results, helping even less-experienced users generate excellent quality data
• Adaptive Correlation produces reliable and repeatable data over twice as quickly, providing a truly representative view of the sample
• M3-PALS with Constant Current Mode measures electrophoretic mobility and zeta potential in high conductivity media

The shapes and sizes of the sets of TiO2 were collected using a scanning electron microscope operating under an acceleration voltage of 5 kV. The crystal phase was investigated by x-ray diffraction under voltage of 40 kV and current of 30 mA. The optical properties of e-TiO2 were studied by ultraviolet–visible (UV-Vis) absorption spectra. Chemical properties were investigated by Raman spectroscopy. Thermal properties were studied by thermogravimetric analysis (TGA). The surface properties and stability were analyzed by ζ potential measurements (Zetasizer Ultra Red Label)… More
