- the light path

The application of unique mixed mode optical fiber technology can greatly reduce optical transmission loss and improve signal-to-noise ratio.

 

Dynamic dispersion principle

Dynamic light scattering is used to detect the fluctuation of scattered light caused by particle Brown motion. The detector transforms the scattered light signal into the current signal, and then through the operation of the digital correlator, the velocity information of the diffusion of the particles in the solution is obtained, that is, the diffusion coefficient. The particle size and its distribution can be obtained by Stockes-Einstein equation.

 

Application system

All particles that can be stabilized in solution as Brown's motion. Typical systems include: emulsion, organic / inorganic particles, natural / synthetic polymer solutions, surfactants, viruses, protein samples and so on. Applications: biology, medicine, nanotechnology, coatings, cosmetics, chemical industry and so on.

 

Zeta potential and its distribution -- laser Doppler electrophoresis +PALS+M3

Malvin patented a new generation of PALS+M3 Technology

Based on the first generation phase analysis light scattering (PALS), a new generation of patent technology has been successfully developed.

Upgrading the electrophoretic scattering hardware to achieve higher signal-to-noise ratio.

Combined with different test modes, the Zeta potential detection of charged particles with low electrophoretic mobility has achieved unprecedented accuracy and repeatability.

The application of M3 patent technology has successfully overcome the influence of capillary electroosmosis on the test, and made the advantages of the capillary sample pool to the extreme, and the average value and distribution curve of the Zeta potential were obtained at the same time in the process of testing.

 

Malvin patented capillary electrophoresis pool electrode assembly

It really avoids cross contamination among different samples.

Combined with MPT-2 automatic Titrant

Realizing automatic measurement of pH potential, salinity and additive trend by Zeta potential.

 

measuring principle

The laser Doppler electrophoresis was used to detect the moving frequency of the scattered light of the sample, and the electrophoretic velocity of charged particles was obtained. The Zeta potential was obtained by using the Herry equation.

 

Applicable system:

The water phase or organic phase is stable or particles that are slowly settling. Typical systems include metals, organic particles, proteins, polyelectrolytes, inorganic oxides, emulsions, slurry, kerosene, ink, carbon black and so on.
