The Power of the Probe: Dynamic Light Scattering Made Easy

Rapid, simple and reliable particle size measurements in suspensions and emulsions without using consumables - all this is possible with Microtrac's unique probe technology used in the Nanotrac analyser series: Nanotrac FLEX and Nanotrac WAVE II. The compact units operate with the Dynamic Light Scattering (DLS) method over a wide concentration range, usually without dilution, to measure particle size, zeta potential, concentration and molecular weight.

Thanks to the unique, flexible probe design and the use of laser-amplified detection in the Nanotrac FLEX, any suitable vessel can be turned into a sample cell. For Nanotrac WAVE II, a wide selection of measurement cells is available. This design enables sample measurements without dilution and without prior knowledge about the particle distribution, based on the Frequency Power Spectrum (FPS) method instead of classic Photon Correlation Spectroscopy (PCS).

The revolutionary fixed optic design of the Nanotrac FLEX probe allows for measurement, for example, in 1.5 ml Eppendorf Tubes® down to one single droplet. As any vessel can be turned into a measurement vessel, the probe can be used at-line as well as in-line to monitor particle growth during a reaction.
