I just read something that I disagree with. I think that UOAs do detect sub-micron particle sizes. For example, even 100% elemental (free ions or atoms) particles would be detected and detected very accurately. The ionization that occurs before detection is used to break down the material to free ions. For example, if NaCl were completely dissolved in water, there are only Na+ and Cl- ions...no NaCl. Spectrographic analysis would detect the Na+ and Cl-.
My apologies for stuffing you full. I've been known to misinterpret people before.
OK in regard to um size - I'm not saying you're wrong, but it does contradict what I've read and experienced. Still - I'm open to that if you can point me to some sources that support your position. I'm not in a position to agree with you yet, but I'm always willing to learn something new. Has the technology changed that dramatically in the last several years?
Is it only the low end? IOW, only the "less than 1um" that we're in debate here? Is the upper end still 5um, give or take a little?
