Using static light scattering (SLS) and the classical Debyeplot, the molecular weight of random coiled polymers up to 5 x 10 5 Daas well as globular polymers and proteins up to 2 x 10 7 Dacan be determined without the necessity for multi-angle measurements.

Measure the size of each population within the sample and separate protein oligomers.

Only seconds to change from batch to flow mode.

The size and intensity are plotted in real time as the material elutes from the column.Īverages, peak positions and estimated molecular weights of each peak are calculated automatically at the end of the measurement. Even samples of very low mobility can be analyzed and their mobility distributions calculated.Ĭonnect the Zetasizer Nanoto your chromatography system for use as a dynamic light scattering detector. This is achieved by a combination of laser Doppler velocimetryand phase analysis light scattering (PALS) in Malverns patented M3-PALS technique. The new Zetasizer NanoZS offers the highest ever sensitivity, accuracy and resolution for the measurement of zeta potential of particles and surfaces. The new Zetasizer NanoZS is the choice for the accurate, reliable and repeatable size analysis of particles and molecules in solution. Non-invasive back scatter (NIBS®) technology takes particle sizing to new levels of sensitivity in the 0.6nm to 8.9 micron range. A direct Internet connection LAN must be available to make use of this facility.

The main advantage of using the Zetasizer 3000HS instead of the Zetasizer IIc is the ability to analyze more diluted samples or more concentrated samples with lower scattering intensity particles.Status, terms of delivery and payment Verification of devices

Regarding emulsions the zeta potential is used to study the chemistry involved in determining whether or not an emulsion will remain stable in the environment where it will be used.

Measurement of zeta potential incombination with these parameters is fundamental in the development and maintenance of optimized water treatment protocols.

In waste water treatment applications the flocculation state of waste water is altered by changes in pH, the addition of chemical flocculants (such as charged polymers) and the presence of aluminium chloride or other highly charged salts.

So, with the measurement of zeta potential in relation to other variables the repulsion between charged particles is indicated and therefore the stability of the colloidal system can be quantified. The zeta potential of the sample will determine whether the particles within a liquid will tend to flocculate or not. The mobility of colloids depend on the characteristics of the solute (electric charge, molecular size and shape) and those of the buffer (type and ionic strength of the electrolyte, pH, viscosity and additives) in which the movement, under influence of an applied current, takes place.

The determination of the zeta potential is performed by first measuring the electrophoretic mobility of dispersed particles and then converting that value to zeta potential by applying electrokinetic theory.
