Product Description Product Description Nanoparticle Size and Zeta Potential Analyzer Integrated of Dynamic Light Scattering DLS, Electrophoretic Light Scattering ELS, Static Light Scattering SLS, and Transmitted Light Detection technology, GD-Zetamax can accurately detects particle size and its distribution, zeta potential, molecular weight of polymer and protein systems, refractive index of liquids, and particulate concentration information, among other parameters. This instrument is designed based on fluctuations of scattered light due to Brownian motion of particles as a function of time. The APD detector converts the scattered light signal into an electrical signal, then processed by a digital correlator to obtain information on the speed of diffusion of the particles in solution. The dimensions of particles, macromolecules, i.e., hydrodynamic diameters DH and their distribution can be obtained through the Stokes-Einstein equation.Features & ApplicationFeatures:* High resolution, it is possible to clearly distinguish the different charged components in mixed samples.* Effective detection of zeta potential information in low electrophoretic mobility samples.* Multi-functional micro cuvette with a sample volume of only 16 μL, which can greatly save the sample volume of precious samples.* VV, VH dual mode, effective detection of anisotropic samples such as sticks or disks.* Single-mode fiber is used for signal conduction to maximize the signal-to-noise ratio.* Microrheology technology, direct and fast detection process and data processing.* Flow mode allows multiple mixed components to be resolved, greatly improving the resolution of particle size testing.Application:* Identification of mixed systems with different charged components by zeta potential test.* Study of the effect of zeta potential of alumina particles of different purities.* Detection of dark brown colloidal suspensions.* Detection of particle size and zeta potential of black carbon of black nanoparticles.* Characterizing the diffusion behavior of club-shaped nanogold.* Detection of BSA solution rheology information.* Detection of BSA particle size distribution.* Detecting Zeta potential information of battery slurry.Detailed Photos Technical SpecificationsParticle Size Detection(Dynamic Light Scattering)Particle Size Range 0.3 nm - 15 μmMinimum Sample Volume 3 μLDetecting Angle 173 °+90 ° + 11.2°Analytical Algorithms Cumulants, common mode,CONTIN,NNLSSedimentation particle size testingDetection Method sedimentationParticle Size Range 1μm-50μmDetecting Angle 0°Sample Volume 1-3mlZate Potential testZeta Range No practical limitationsElectrophoretic mobility range > ±20 μ.cm/V.sConductivity range 0 - ≥270 mS/cmZeta Tested Particle Size Range 1 nm - >120 μm Molecular TestingMolecular Range 342 Da - 2 x 107 DaMicrorheology TestingTesting CapabilityMean square displacement, complex modulus, modulus of elasticity, viscous modulus. creep modulusTrend testing Mode Time & temperatureConcentration DetectionDetection Method LEDLSTesting Capability Volume fraction and number concentrationRefractive index testDetection Method Wedge cell sample refraction, no tracer particles requiredDetecting Angle 0°RI Range 1.2-1.6Precision Better than 0.1%Minimum Sample Volume 380 μLsystem parameterTemperature -15°C - 120°CCondensation Control Dry air or nitrogenLaser 50 mW High-performance solid-state lasers , 671 nm(Different wavelength lasers available)CorrelatorFast,middle fast,,slow multimode modes. 25 ns sampling, max 4000 channes,1011 Dynamic Linear RangeDetector APD (high performance avalanche photodiodes)+PD+CMOSLight Intensity Control 0.0001% - 100%, manual or auto About UsChongqing Gold Mechanical & Electrical Equipment Co., LTD 2000Established in 2000, we have more than 20 years experience is all kinds of geophysical equipment. We provide detectors, seismograph, borehole camera, magnetometer and geophysical logging deivices.2008Our company developed very fast in this period, and we also expand our products scale. We can also provide drilling rigs, water level meter, inclinometer, GPS, total sation and so on.2013As their are more colleagues joined into our team, our company moved to China Resources building. And at there, our company acheived much more turnover and it is still in growing2023We are looking for more potential product and business relationship with anyone or any company in the world. What we are glad to see is a win-win situation.
