In answer to Michael Leavitt's question and Marshall Dudley's reply.... the only way we know to measure particle size is by imaging them in a calibrated Transmission Electron Microscope. We offer such services on our web site at natural-immunogenics.com where you can also see (somewhat feeble) reproductions of such micrographs. I chararcterize them as feeble because the high resolution scans we got of the negatives for those that are published on the site range from 39mb to 52mb, hardly anything you would want to email....
Stephen ps we also do osmometry to "catch" the use of electrolytes in preparations called colloidal silver (though even a "water" can be an electrolyte to some extent if it is impure). ----- Original Message ----- From: Marshall Dudley <[email protected]> To: <[email protected]> Sent: Friday, March 31, 2000 5:14 PM Subject: Re: CS Quality > I wish there were, but I have not found it yet. > > Marshall > > Michael Leavitt wrote: > > > Hi Marshall, > > If we make good clear Cs, how do we know what size the particles are?
