Joseph,

To make HVAC CS one needs a 12 kv 60 ma. neon sign transformer and a brew cell,
Some use a one gallon glass pickle jar but I use a two gallon fish aquarium. One
needs a plastic over for the brew cell. Remember that 12,000 volts wants to jump
everywhere so long insulation paths are required.

1.) 2 wet electrodes space about 3" to 4" with about 5" to 6" inches wet. either
#12, #14, or flat sheet is ok.
    The product is not very stable and many times it goes yellow.

2.) One wet electrode as above and one electrode about 1/4" above DW surface.
When power is connected the DW will cone up around the electrode. Makes a
slightly best grade of CS.

3.) ARC process:

    A.) submerged arc, work best with cold DW some actually use DW at about 40
deg. F or less. The electrodes are inside of pyrex glass tubing except for may 
be
1/8" wet. Works fast but makes large particle CS with a medium T.E.

    B.) Arc in gas ambient. With this process the dry electrode is mounted on a
bakelite sheet 3" X 3" to contain the heat that would melt and set fire to the
plastic cover. The gap between the DW and the dry electrode  is 3/8". Larger 
than
in "A" above.
If the ambient in the head space is air then a large amount of NO3 is produced.
Now the inital measurement of NO3 is deceptive as it will be about 3 ppm, but 
the
anion formed is ozone which over 24 hours will convert NO2 to NO3 and the value
will be about ten times the initial reading ( I have about ten runs to verify
this).  If the ambient is CO2 formed from dry ice then the NO3 will be less 4 
and
stay constant as no ozone is formed.

At 12 kv and 60 ma. it takes 3+ hours for 15 ppm and 4 hours for 20 ppm. The CS
is crystal clear withalmost no T.E. what is there can only be seen in a room so
dark that you can not see your hand in front of your face. It is almost 95%ionic
silver solution. The water is also structured as is visible in the T.E. M. that 
I
have had made of this process.

The pH is about 4 as measured with a digital pH meter. The conductivity can vary
fro 70 to 180 uS/cc.

I hope this answers your questions. If not contact me off list.
