| Dynamic Light Scattering Instrument (Particle size, Zeta Potential, Molecular weight) |
| General Features: Dynamic Light Scattering (DLS) must be capable to measures particle and molecule size, from 0.3 nm to 10 µm.Electrophoretic Light Scattering (ELS) must be capable of measuring 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 and molecular weight measurements.M3-PALS with Constant Current Mode, for zeta potential and electrophoretic mobility measurements.Software suite, for simple and flexible method set-up and data analysisAdaptive Correlation, for faster, more reproducible sizing measurements with less sample preparation.Deep learning-based 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.Blue Label for routine sample investigation such as metallic colloids, metal oxides and pigments.Red Label for more challenging sample types, such as proteins, surfactant solutions and low solid content samples.On-site upgradeability to Ultra-model.The addition of Auto titrator enables study of the effect of changes in pH.A range of disposable and reusable cells are available to optimize the measurement in terms of sample volume and concentration. |
