Alternative laser, 50mW at 532nm for samples incompatible with the standard 633nm laser.Optional flow mode capability to enable use as a GPC / SEC size detector.Automation of measurements using an autotitrator option.
#MALVERN ZETASIZER NANO SOP 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 M3-PALS technology.Size measurement from 0.3nm (diameter) to 10 microns using 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 Zetasizer Nano ZS 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. The high performance of the Zetasizer Nano ZS also enables the measurement of the molecular weight and second virial coefficient, A2, of macromolecules and kD, the DLS interaction parameter. It is used for the measurement of the size, electrophoretic mobility of proteins, zeta potential of colloids and nanoparticles, and optionally the measurement of protein mobility and microrheology of protein and polymer solutions.
