I'm no chemistry guru so I can only speak in laymans language.
The drop or reduction in ppm readings is a good indicator of purity of water
used, don't be surprised if that reading drops almost 50% [based on literature
and evidenced from experience].
Some people may be surprised to see their readings seemingly drop significantly
over time until the solution reaches a point of stability, I take that reading
drop as a complement to the quality of water I'm using. If it failed to drop
by an appreciable amount...then I have something else in the water besides
silver. I believe the amount it drops is proportionate with the ppm level at
cessation of the brewing process {based on my own experiences, the higher the
end ppm result on production cessation, the greater the drop in reading} and I
have had it drop near on 50% from initial reading on the day it was produced.
Meters only give me a point of reference to shut my process down, I don't rely
on them for any accuracy in silver content, just a ballpark figure {commonly
referred to as a 'guesstimate'}.
*Immediately* upon cessation of the brewing process the solution will be at
it's highest in ionic content {positively charged silver ions} and as time goes
by {few days praps} there will be a number of ions colliding with other ions
forming atomic clusters {these would be called particles or particle clusters I
guess}.
The distinction between two solutions I referred to is just that...a solution
which is high in ionic content, and a solution that has stabilized over time
and has lost some of those ions to particle clusters, and I use whichever I
consider will be most efficacious for a given circumstance, hence my comment
about 'oils ain't oils' and 'EIS/CS ain't EIS/CS'.
That's my backyard scientists way of explanation <g>, I'll leave it to the
chemistry guru's to explain in better language and/or clear up any errors. But
all I've said here is based on my experience over several years involvement
with this 'stuff', not saying it's 100% accurate, just my experience.
