Fred, the conductivity of the solution will relate directly to it's concentration in PPM- the total quantity of water is'nt an issue; electrode immersed length, separation, applied voltage, and temperature will all affect the initial current reading, but once you test a solution of known concentration in your setup, you can then always stop the generator process at the same current reading to get the same concentration. (With the bulb in circuit on most 27 volt systems, the current is limited to what that bulb will pass, 35 to 40mA, so the current won't climb any higher - but as I pointed out in the previous post, I use a cutoff of 8mA at 15 volts supply with 3-1/4" of electrodes immersed, separated by 1/2"between them. Every batch run at about 180 degrees F comes out the same concentration - I'll try to have lab results posted by the end of the week. Further Note: Beyond this current level / concentration, the plateing out of the "silver sludge" on the cathode becomes excessive; you're turning your silver anode into throw-away sludge, instead of adding much mors colloidal silver into the solution. At higher current levels, gas production at the cathode causes more of the "sludge" to be dispersed into the water (watch it happening!), requiring more thorough filtering.... (When using salt or baking soda, the whitish Silver Chlorides & Silver Bicarbonates are too fine to filter out by most normal methods.) Questions & Comments always welcome! Bruce Stenulson Applied Technology I'll try to provide a more complete approach within a week. Bruce -- The silver-list is a moderated forum for discussion of colloidal silver.
