![]() Temperature control from -5 ☌ to 110 ☌ ± 0.1 ☌. This book provides a concise introduction to the theory behind light-scattering and zeta-potential measurements, along with practical tips for preparing samples, choosing measurement parameters and interpreting results.40 mW diode laser (nominal 640 nm wavelength).Three measurement angles: 15°, 90°, and 173°.Concentration range: 0.1 ppm to 50 mg/mL, depending on sample refractive index.Size range: 0.3 nm to 10 µm depending on refractive index and concentration. ![]() Multimodal & unimodal size distribution software As in the related DLS ( dynamic light scattering) method, the suspension is illuminated by a light source, generally a laser of a visible wavelength.Rapid and accurate protein & nanoparticle size distributions.With 4-pumps, a pH probe and the possibility of temperature control, this accessory allows user to measure the variation of zeta potential of their sample with concentration of an additive (such as acids, bases, surfactants, dispersing agents, salts, etc.) Features at a glance Sizing The instrument has also an autotitrator unit with a volume of 20 mL. The instrument also has the capacity of zeta potential detection by Phase Analysis Light Scattering (PALS) measurements for samples with low mobilities. Note: We will be closed on June 20 for Juneteenth shipping dates may. The measurements are based on the principles of Dynamic Light Scattering (DLS) for particle sizing and distribution, and based on Doppler velocimetry (electrophoretic light scattering or ELS) for zeta potential measurement. Table of contents: Spectroscopic Analysis (UV-Visible Spectroscopy) Transmission Electron Microscopy (TEM) Dynamic Light Scattering (DLS) Zeta Potential Inductively Coupled Plasma Mass Spectrometry (ICP-MS) Dark Field Microscopy Aerodynamic Particle Sizer (APS) Scanning Mobility Particle Sizer (SMPS) Matrix-assisted La. The NanoBrook Omni particle size and zeta potential analyzer incorporates all you need for fast, routine, sub-micron measurements of size and zeta potential. Regarding the optimized measurement technology, the STABINO. It is possible to measure the zeta potential of particles in the range of 0.3 nm to 300 m in a concentration range of up to 40 volume percent. Dynamic light scattering: Brookhaven Instrument NanoBrook OmniĬontact: violeta.toader mcgill.ca (Violeta Toader) - Location: OM 21 The STABINO ZETA has a high resolution and data point density, which allows very fast, precise and reproducible zeta potential measurements.
