The BeNano 180 Zeta Max is a state-of-the-art nanoparticle analyzer that combines light scattering and transmission techniques. It provides precise measurements of particle size and concentration, zeta potential, molecular weight, refractive index, and rheological properties, all within a single compact system. MEASUREMENT MODES Refractive Index Backscattering Dynamic Light Scattering Collects more scattered light than 90° optics, improving sensitivity to small particles. The auto-adjusting measurement position ensures accurate size results even at concentrations up to 40% w/v. Precisely distinguishes...

Most light passes through the sample without being scattered Laser Scattered light Size Measurement Dynamic Light Scattering (DLS), also known as Photon Correlation Spectroscopy (PCS) or Quasi-Elastic Light Scattering (QELS), is a technique used to determine particle size by analyzing the Brownian motion of particles in a dispersion. Intensity Intensity Intensity Intensity Intensity Fluctuations of Small Particles 16000 14000 Intensity Intensity DLS is based on the principle of Brownian motion, which relates particle size to velocity—smaller particles diffuse more rapidly, while larger particles...

Zeta Potential Measurement Stern layer Positively Charged Particle • High zeta potential Phase Analysis Light Scattering (PALS) is a more advanced technique than traditional ELS, which has been further developed by Bettersize to measure the zeta potential. Zeta Potential Distribution Surface potential Zeta potential High Zeta Potential Low Zeta Potential 3 Potential Distribution at Particle Surface • Effectively measures the zeta potential of particles whose charge approaches the isoelectric point • Flocculation, aggregation, sedimentation • Accurate measurement of samples with low electrophoretic...

Molecular Weight Measurement Concentration (mg/mL) Debye Plot Static light scattering (SLS) is a technique that measures scattering intensities to calculate the weight-average molecular weight (Mw) and the second virial coefficient (a2) of a sample using the Rayleigh equation. • Non-invasive technique • Suitable for particles dissolved in liquid • Measures molecular weight of samples smaller than 30 nm • Provides second virial coefficient A2 indicating the intermolecular interactions where c is the sample concentration, 6 is the detection angle, R6 is the Rayleigh ratio used to characterize the...

Flow Mode Measurement DLS flow mode provides a high-resolution size result of a complex, polydisperse system. When combined with front-end separation equipment such as GPC/SEC or FFF, particles are separated into monodisperse fractions and flow through the BeNano in sequence by size. The size of each fraction is continuously measured and summed into a high-resolution size distribution. BeNano can acquire RI or UV signals, offering a more accurate volume and number distributions independent of algorithm compared to a batch-mode measurement. • Size resolution as high as 1.3 : 1 • Size distributions...

Refractive Index MeasurementConcentration Measurement The BeNano 180 Zeta Max can determine the refractive index (Rl) measurement of liquids with outstanding precision. A patented wedge-shaped cuvette holds the liquid sample while the CMOS detector measures the deflection of the light path after it traverses the liquid to calculate the RI The BeNano measures particle volume fraction and number concentrations in particles per milliliter (particles/mL) for each population through the patented LEDLS technique. The incident light passes through the sample and reaches a photodiode detector, which...

Sedimentation Size Measurement The BeNano 180 Zeta Max provides particle size results based on the sedimentation method. The sedimentation rate of particles is directly related to their size, with larger particles settling faster. The PD detector monitors the changes in transmitted intensity over time, enabling the determination of particle size and distribution for particles up to 50 microns. pH Autotitration Measurement BAT-1 Autotitrator • Volume-weighted Mean Diameter D[4,3] • Size Distributions Weighted by Volume FEATURES & BENEFITS • Expands size measurement range up to 50 pm • Suitable...
