Microtrac - Model Nanotrac Wave II -Nanoparticle Size Analyzer
Microtrac’s NANOTRAC Wave II / 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 / 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).
- 180° backscatter DLS setup
- Stable fixed optics sample interface – no adjustments required
- Rapid field reversal prevents electro-osmosis
- 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
All NANOTRAC WAVE series analyzers use the same revolutionary probe technology for DLS measurements. Utilizing our Laser Amplified Detection method, repeatable and stable particle size measurements for all types of materials are provided.
The NANOTRAC WAVE II series can also calculate the sample concentration through the use of the power spectrum and the resulting loading index. Depending on the distribution calculation, concentration will be displayed in appropriate units such as cm3/ml or N/ml. It is also possible to calculate the molecular weight by either the hydrodynamic radius or a Debye plot.
The NANOTRAC WAVE II particle analyzer has multiple reusable samples cells in different sizes. There is a standard and micro volume Teflon cell for a wide range of materials. For more difficult to clean samples, there is a standard volume stainless steel cell, as well as a large volume stainless steel cell.
The NANOTRAC WAVE II Zeta particle analyzer has a special reusable zeta cell with an electrode for running zeta potential measurements. Sample cells listed for the Wave II are also compatible with the zeta model.
