How the Power of the Probe Simplifies Dynamic Light Scattering

The unique probe technology in Microtrac’s Nanotrac series analysers, Nanotrac FLEX and Nanotrac WAVE II, provides rapid, simple and reliable particle size measurements in suspensions and emulsions without using consumables. These 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.

The cutting-edge, versatile probe design and the use of laser-amplified detection in the Nanotrac FLEX, allows any suitable vessel can be turned into a sample cell. A wide selection of measurement cells is available for the Nanotrac WAVE II. 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.
