You must have mistaken me for someone who knows what he's doing ;-)). My math skills are basic at best. Well, I muddled through per your instructions and Wppot32 and Mercury and found that the average current was only .220 ma. So the calculated ppm was 6.23 and the actual was probably a lot lower. Actual time was 2.5 hours @ 12ounces distilled water.
Remember I said that I calculated the series resistor without regard for the cell resistance. The cell resistance at the end was 20K ohms which was equal to the series resistor. The final current was about .444ma. So this was about half of the 1ma I was shooting for and obviously the beginning current was a lot less, about .116ma. (Voltage = 18V; Resistor = 20K ohm; beginning cell resistance = 136K ohms, end = 20K ohm) But, from your reaction, the description of my salt test gave you a clear indication of the ppm of my CS or EIS.

Can you try integrating the current vs time curve to get the average current, then do the Faraday calculation? An example of integrating a current/time curve is on my web page in Figs 3 and 4: http://www3.sympatico.ca/add.automation/misc/130vdc.htm The integral intercepts the right Y-axis at a value of about 32. The time is 30 minutes, so the average current is 32/30 = 1.066 mA You can do this in WPlot. Just give it a table of current values and the time since starting the brew. Just plug that into Mercury and let us know the predicted ppm. I'll bet it is pretty low:) Best Regards, Mike Monett -- The silver-list is a moderated forum for discussion of colloidal silver.
