Correct.
Optical counters are worthless with opaque oil
You sure? How do they work? I've only used Malvern particle sizers in my past in pharma QC. The sample was diluted to a proper opacity/translucency to allow light to pass through an acceptable range and then the machine counted the particles. It shot a laser through the sample and then some hocus pocus about where the laser was deflected and whatnot and poof, you had a particle size analysis.
