Hi Trem, 1. ANY HVAC system will make both NO and NO3 due to the nitrogen adsorbed in the DW. Stephen Quintro distills under Argon, transports under Argon and brews under Argon. That is a mess. I have an Argon tank but its not worth the effort.
2. It easiest method for the detection of NO3 is through pH. If the pH is 6 or above then no worry, but when it gets down to around 3 or 4 then one should check for NO3. 3. The "correction factor" for use of a PWT is generally due to the formation of a weak acid. On the wide anode, narrow cathode sample that I had Stephen check, the conductance was 12 and the PPM was 10. The pH was 6.58. As stated I have measured 1 ppm of NO3 in 37 v CS. I can't answer your question as to the electro-chemistry involved, but a correction factor to 1.6 or more for a PWT would cause me to wonder about the NO3 value. In the hundreds of samples that I have checked there have been less than a dozen the pH over 6. I generally do not check LVDC for NO3 as the limits have been very low. This I do know; with equal sized anode and cathode the ratio of Cond. to PPM is large maybe 1.8 to 2, and pH's 5 or less. With a ratio of anode to cathode of 8 to 1, the Cond. to PPM can be about 1.2. and the pH's are over 6. I find that conductivity changes during the first 24 hours. What I monitor during the test brews is not always the same after a few hours. Why? I do not know. I will try to find out. In talking to Stephen we both agree that there are some factors in making CS that we are not even aware of! There is one area that I have just touched on and that is the energy required to make CS. If you have Wplot32.exe you can put plot on the tube and look at the top bar there is an option "transformations". With this one can integrate the area under the current curve and get a value dimensions of MA- TIME. By adjusting the units and multiplying by voltage on can get an energy equivalent to make the CS. The voltage multiplier is not required for a constant voltage study. To do this for your system will require a little more math as there is an additional integral required for the change in voltage. But the MA-TIME comparison is wild. I will try and put something together for you s I have the data but have not done the analysis. Sufice it to say when I did a casual look I could not rationalize what I saw. "Ole Bob" -- The silver-list is a moderated forum for discussion of colloidal silver.
