Options also include full zeta potential capability and higher power lasers for very small particle sizes. Zetasizer Nano ZS 90 Nanoparticle Size Analyzer is used for routine measurements of particle size distributions from about 1 nm to about 6 nm in any liquid by using Dynamic Light Scattering (DLS). The systems measure size using dynamic light scattering, zeta potential using electrophoretic light scattering, and molecular weight using static light scattering. Particles from less than a nanometer in size to several microns can be analyzed by a range of variants.
Automation of measurements using an autotitrator option.
#Malvern zetasizer nano zs principle software#
Research software option to give access to further features and analysis algorithms for the light scattering specialist.21CFR part 11 software option to enable compliance with ER/ES.A ‘Quality Factor’ and ‘Expert Advice System’ gives the confidence of having an expert at your shoulder.Optional protein calculators, including protein charge, A2, kD, and molecular shape.Sample concentrations from 0.1ppm to 40%w/v.Protein size measurement as dilute as 0.1mg/mL (Lysozyme).Microrheology option to measure viscosity and viscoelasticity.Molecular weight measurement down to 980Da.Zeta potential using patented M3-PALS technology.Size measurement from 0.3nm (diameter) to 10 microns using patented NIBS (Non-Invasive Back Scatter) technology.Particle and molecule size, translational diffusion, electrophoretic mobility, zeta potential of particles at high and low concentrations, viscosity and viscoelasticity of protein and polymer solutions, concentration, MW, A2, kD.Īn optional accessory enables measurement of the zeta potential of solid surfaces. The flow mode option enables the system to be connected to an SEC or an FFF system to use as a detector for the size of proteins or nanoparticles.Ī choice of cuvettes are available, from disposable single-use to specific cells for viscous or high concentration samples or measuring the zeta potential of surfaces. In addition, a microrheology option is available for measuring sample viscosity and viscoelastic properties, as well as a Protein Measurement option for protein mobility measurements. Using Non-Invasive Backscatter optics (NIBS) it has significantly better performance than systems using 90 degree scattering optics. The ZSP also incorporates a zeta potential analyzer that uses electrophoretic light scattering for particles, molecules and surfaces, and a molecular weight analyzer using static light scattering. The Georgia Tech Zetasizer Nano ZS, located in the Georgia Tech Biocleanroom, is a high performance two angle particle and molecular size analyzer for the enhanced detection of aggregates and measurement of small or dilute samples, and samples at very low or high concentration using dynamic light scattering with ‘NIBS’ optics.
