Temperature control range: 0☌ – 90☌ +/-0.1Įxcellent condition.

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

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

Measurement range: 3.8 nm – 100 µm (diameter).

Measurement range: 0.3 nm – 10.0 µm (diameter).

From this the average molecular weight and second virial coefficient A 2can be calculated, which gives a measure of molecule solubility. In this technique, the scattering intensity of a number of concentrations of the sample is measured, and used to construct a Debye plot.

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 Scattering (DLS) is used to measure particle and molecule size.The Zetasizer Nano ZS incorporates three techniques in a single compact unit:
