Overview
Zetasizer Ultra provides the ability to measure particle and molecule size, particle charge, molecular weight and particle concentration in a liquid medium using light scattering and laser doppler electrophoresis.
Key Features
- Multi-Angle Dynamic Light Scattering (MADLS) for absolute confidence in particle and molecular size distribution analysis
- Dynamic Light Scattering (DLS) measures particle and molecule size, from 0.3 nm to 10 µm
- Electrophoretic Light Scattering (ELS) measures the zeta potential of particles and molecules, indicating sample stability and/or propensity to aggregate
- Non-Invasive Back Scatter (NIBS) optics for versatile, high sensitivity, particle and molecular size measurements
- Simple, per-peak concentration / titer measurements
- 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
- M3-PALS with Constant Current Mode for zeta potential and electrophoretic mobility measurements
- ZS Xplorer software suite for simple and flexible method set-up and data analysis
- Adaptive Correlation for faster, more reproducible sizing measurements with less sample preparation
- Deep Learning empowered data quality system for assessment of any size data quality issues, with clear advice on how to improve results
- Optical filter wheel with fluorescence filter to allow measurement of fluorescent samples without impairing overall system sensitivity. Also includes polarization filters for DDLS measurements
