Malvern Instruments Zetasizer Nano - Zeta potential measurement
1.Can we measure the Zeta potential of AOT/water/isooctane reverse micro emulsion system by varying the water content of system? The system contains iron oxide nanoparticles of size 3nm to 16nm (by TEM) surrounded by AOT surfactant as shell dispersed in Isooctane.
2. Can we compare DLS size results with Small Angle X-ray scattering size results? If possible, how are they comparable? Help this member.
Micromeritics Elzone II 5390 - Coincidence too high
Although the elektrolyte was filtered (0.1µm) the coincidence of the elektrolyte without sample is at 80%. Two weeks ago it was at 0.01%. What can be the reason? Respond by clicking here.
Beckman Coulter Multisizer 3 - Hydrophobic Material
A client gave us a sample and requested a particle size distribution on it. The sample just happens to be hydrophobic so, all the particles float straight to the top of the electrolyte in the beaker and will not stay submerged, so an analysis cannot be conducted. Would it be ok to use another liquid, other than the electrolyte, for the analysis? If so, what? Or, do you know of something I can add to the beaker which would remove the sample's hydrophobicity? Share your knowledge.
