Hello Ode
you can make excellent colloidal silver with a Microwave oven
I have been using one for years ..There is no danger of High voltage
as the colloidal silver is made inside of the microwave and the door will
not open until the timer has stopped..The colloidal silver is made with
from 2400 to 3600 volts DC and is water clear up to about 20ppm..The
electrodes
need to be cleaned every two minutes..You can make one and one half gallons
in about 12 minutes depending on PPM required..Particles are very small
on a spectrometer..use 1/4 or 1/2 inch wide silver rods 6 inches long.

Really high voltages gets those ions away from the electrodes really
fast.
That's how most of the commercially sold EIS is made as *time is
money*..but that much voltage can shorten your time on Earth even faster.
No generator maker in his right mind would sell one to a "consumer".

What do you think about the guy who says he makes 40 ppm in a minute or
two using a microwave oven 3600 volts?
Or something like that.
If that really works, then I should be able to make pretty good EIS with
the 2000v electrophoresis power supply in a very short time. Maybe I have
been over-cooking the stuff trying to get higher ppm...?

Hello Dick,
uS is micro siemens, and is a measure of the conductivity of water. Since
the electrodes are spaced 1 cm apart the results come out in uS/cm.
Some instruments are set up to display PPM. They do this by measuring the
conductivity of a salt solution, then multiplying it by a factor number to
arrive at PPM. If you are measuring the same salt concentration that the
meter was set up for, you will get reasonably accurate PPM results.
Unfortunately, none of the standard calibration solutions are set up for
EIS.
Trem (SilverGen) made several batches of EIS, tested them with a uS meter,
then sent them off for laboratory analysis. He uses a Hanna PWT meter.
Since EIS is mostly ionic, and since the PWT meter mostly responds to ions
rather than particles, the theory is that the uS value should be close to
the actual PPM of silver in the solution once correction factors are
applied.
The process involves measuring the water you are starting with. When your
batch is finished, let it sit for a day or so, then measure it and
subtract
the initial reading you got for your water. This should be an indicator
of
the ions in the solution. When Trem got the lab sample reports, he
discovered that a "typical" batch has about 85% ions and 15% particles.
He
suggests using a 1.2 correction factor for EIS made with his generators.
While fine in theory, there is some controversy over this. Ode has also
had
lab samples done, and does not find the correction factor valid. On top
of
that, the lab people say that a conductivity measurement will only provide
a
"ball park" estimate of the concentration of silver in solution, and the
only way to know for sure is to spend the $200/sample and have it
analyzed.
This is why I gave my results in uS/cm rather than PPM.
The main question is to determine what ion contamination can be introduced
into the solution when you heat it up. If there is no contamination being
introduced, then it is reasonable to believe the concentration is being
increased by removing water from it.
