As I said I would, I spent a couple hours on the phone today to labs that can check silver.
For 15 to 20 dollars they will check for PPM. The big expense comes when checking particle size with an electron microscope. Do you make your silver with low voltage DC or high voltage AC ? When I was making it with lvdc I used a Hanna TDS meter. Now that I use only hvac it can't be used to test for PPM. I plan to send it to one of the labs I spoke to today for PPM only.

Can anyone recommend a good place to send samples of my CS to get the true
PPM, particle size, and whatever
other info is pertinent? Thanks in advance!
Many labs cannot accurately measure colloidal silver. I sent a sample
to a major lab in Albuquerque. It returned as 0.6 Mg/L. Old Bob, Bruce
Marx, and myself tested it to be about 10 Mg/L. Bruce said, "Just
looking at the Tyndall told me it was about 10 PPM."
