What the NANOTRAC WAVE II is
The NANOTRAC WAVE II is a benchtop dynamic light scattering analyzer from Microtrac that measures nanoparticle size, zeta potential, molecular weight and concentration with one fixed optical probe. Laser light at 780 nm passes through a sapphire window into the sample; part of it is reflected back at the window and mixes with the light the particles scatter at 180°. This Laser Amplified Detection gives up to 106 times the signal-to-noise ratio of photon correlation spectroscopy, and a frequency power spectrum calculation returns narrow, broad and multimodal distributions without any prior information about the sample. Zeta potential is measured on the same optics: an electric field is applied, and the instrument reads particle mobility and polarity from the change in the power spectrum.

What it tells you about a nanoparticle dispersion
Size alone does not say whether a dispersion will stay dispersed. These are the numbers that do:
| Size distribution | narrow, broad or multimodal, with no model to choose; results in as little as 30 seconds |
| Zeta potential | the electrostatic repulsion between particles — positive or negative, and how strong |
| Zeta versus pH | where the charge goes to zero and in which pH range the dispersion stays charged |
| Molecular weight | by hydrodynamic radius or Debye plot; the second virial coefficient shows whether molecules tend to aggregate |
| Concentration | from the loading index, in cm³/mL or particles per mL |
Microtrac application notes show inks of all colors measured at high concentration, where a bimodal distribution stands out clearly, and molecular weights of dextran and polyethylene oxide determined by Debye plot on a NANOTRAC instrument.
The probe also takes concentrated samples up to 40 %, sample dependent, so in many cases the dispersion is measured close to its real state instead of after heavy dilution.
Three measurements on the same optics
Where the NANOTRAC WAVE II stops — and what to take instead
The NANOTRAC WAVE II stops at 10 µm for size and at 10 nm – 20 µm for zeta potential. Its conductivity range is 0 – 10 mS/cm and its titration is pH only. For dispersions with high salt content, polyelectrolyte or salt titrations, or charge on particles up to 300 µm, the STABINO ZETA measures streaming potential with conductivity up to 350 mS/cm. If you need to measure inside a reaction vessel or a pipe, the dip-probe NANOTRAC FLEX does that. Above 10 µm, laser diffraction is the method: see the BLUEWAVE or the SYNC.
