Microtrac – Dynamic Light Scattering (DLS) – Nanotrac Wave Series
Microtrac MRB’s NANOTRAC Wave II / Q / Zeta is a highly flexible Dynamic Light Scattering (DLS) analyzer which provides information on particle size, zeta potential, concentration, and molecular weight. It allows faster measurements with reliable technology, higher precision, and better accuracy. All of this combined into a compact DLS analyzer with a revolutionary fixed optical probe.
With the unique and flexible probe design and the use of the Laser Amplified Detection method in the NANOTRAC Wave II / Q / Zeta, the user is able to choose from a wide array of measurement cells that satisfy the needs of any application. This design also allows measurements of samples over a wide concentration range, monomodal or multimodal samples, all without prior knowledge of the particle size distribution. This is made possible through the use of the Frequency Power Spectrum (FPS) method instead of classical Photon Correlation Spectroscopy (PCS).
Key Features
- 180° backscatter DLS setup

- Robust mobility calculation as a function of power spectrum ratio
- High concentration zeta potential measurements
- Sample concentration and molecular weight determination
- Universal solvent compatibility
- Frequence Power Spectrum calculation model instead of PCS
- Laser Amplified Detection – high signal to noise ratio
