Its interesting that you mention these gadgets. Out of interest I've
been reading up on them recently. They seem a pretty difficult way to
measure ionic silver, way beyond the know-how of most of us, and not
simply a matter of dipping an EC or ppm meter into a solution like we
normally do. It appears they require lots of calibrating in a
solution of known ionic silver content (which would present a few
obvious problems I would think). And it looks like an investment of
quite a few thousand dollars would be required to get set up properly
with an ion selective measuring system.
Lots of info here about them...

However its interesting to note that Frank Key's Colloidal Science
Lab does not use ISE's to measure ionic content. I would think such a
device would be right up his alley if they work as imagined.
Perhaps theres a problem with actually using them to measure ionic
silver that I have not grasped.

A selective ion probe meter will give accurate silver ion
concentrations from 0.1ppm to 10,000 ppm. Combined with the Malvern
results and a total solids determination using dry weight, along
with sem photos after ultracentrifuging, you will be able to
calculate the absolute ratio of ions to particulate along with a
good idea of particle size distribution. There are analytical
balances that are accurate in these ranges of concentration. This
is not conjecture.
