The results were processed using the Dispersion Technology Software 6.2.

Temperature control range: 0вЊ вЂ“ 90вЊ +/-0. Photon correlation spectroscopy was used in National Research Centre Central Lab to estimate the Z-average hydrodynamic diameter of the analysed samples at 25 0.1 C using a Zeta Sizer Nano ZS (MalvernInstruments Inc., Southborough, MA). We used a Zetasizer Nano ZS analyzer (Malvern Instruments) to analyze the zeta.

Minimum sample volume:В 12ВµL (3-5 sample concentrations required).

Minimum sample volume: 150 ВµL (20 ВµL using diffusion barrier method).

Measurement range: 3.8 nm вЂ“ 100 Вµm (diameter) The Zetasizer Nano provides integral Peltier temperature control over the range of 0 to 90 вЊ to +/-0.1 вЊ (0 to 120 вЊ for the High Temperature model), in addition to rapid system warm-up and the ability to quickly change temperature both features that can be helpful for studies at elevated temperatures.

Measurement range: 0.3 nm вЂ“ 10.0 Вµm (diameter).

From this the average molecular weight and second virial coefficient A 2can be calculated, which gives a measure of molecule solubility. Dynamic Light Scattering is used to measure particle and molecule size.

The Zetasizer Nano ZSP incorporates three techniques in a single compact unit, and has a range of options and accessories to optimize and simplify the measurement of different sample types.

Inserting the CD into a system configured to auto-run a CD will run the installation program automatically. In this technique, the scattering intensity of a number of concentrations of the sample is measured, and used to construct a Debye plot. Malvern Zetasizer ZSP - dynamic light scattering (DLS) system. Zetasizer Helix rdAny 3 Party Software / Interfaces Installation Instructions The software suite comes on an auto-loading CD-ROM.

Static Light Scattering is used to determine the molecular weight of proteins and polymers.

An available surface zeta potential accessory uses tracer particles to measure electro-osmosis close to a sample surface to calculate the zeta potential of the surface. An electric field is applied to a solution of molecules or a dispersion of particles, which then move with a velocity related to their zeta potential.

Laser Doppler Micro-electrophoresis is used to measure zeta potential.

Measurement of size as a function of concentration enables the calculation of k D, the DLS interaction parameter. This technique measures the diffusion of particles moving under Brownian motion, and converts this to size and a size distribution using the Stokes-Einstein relationship.

Dynamic Light ScatteringВ (DLS) is used to measure particle and molecule size.

The Zetasizer Nano ZSВ incorporates three techniques in a single compact unit:
