#Malvern zetasizer nano ph titration software
Alternative laser, 50mW at 532nm for samples incompatible with the standard 633nm laser. While at the Malvern exhibit at Pittcon quite a few visitors to our booth have asked where to find the latest software version for the Malvern Zetasizer Nano series.As is evident from the pH titration, the isoelectric point of the wall is near pH 4.5. Optional flow mode capability to enable use as a GPC / SEC size detector. A typical pH dependence of the wall zeta potential for the DTS1060 disposable capillary cells used with the Zetasizer Nano system is shown in the figure below.Automation of measurements using an autotitrator option.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.The pH value remained constant at 7 during the titration. A ‘Quality Factor’ and ‘Expert Advice System’ gives the confidence of having an expert at your shoulder. measured using Zetasizer Nano ZS (Malvern Instruments, laser: 4 mW He-Ne, 633 nm).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.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. 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. Zetasizer Nano ZS for size, zeta potential, protein mobility and microrheology - Performance, simplicity, versatility. © Malvern Panalytical 2018 Zetasizer Nano & APS Submicron Light Scattering Size, Charge, and Interaction Parameters Proteins, peptides, biopolymers, and.
