I know little of zeta potential. I think it has to with the sum of the attractive and repulsive forces influencing colloids. In silver sols, it means the likleyhood of them combining into larger particles. Most commentators believe that the smaller particles are responsible for the anti-pathogenic qualities.
The strength of that charge may also relate to the potency of a particle. Some commercial makers also believe that cooler water makes smaller particles. I use a HVAC generator, and when I run it for extended periods, the sol is golden-tan. Since it has been demonstrated that very low dilutions of fine-particle CS are effective against most pathogens, I prefer a lower concentration of small particles and large dosage volumes. Thank you for the description of your generator, I have added it to my collection.

Here are the basic components of my generator (courtesy of educate-yourself.org): 1. a two liter erlenmeyer flask with rubber stopper, through which is set a thermometer and the two electrodes 2. a double boiler into which the flask is set 3. an electrical converter which outputs 27volts DC During the process the temperature is kept just under boiling. Polarity is switched every minute, in order to prevent current runaway. This also minimizes the amount of silver oxide that collects on the electrodes. I generally run the generator for three or four hours which yields ~200ppm, but if one were to run it for a couple of days they'd get upto ppm in the thousands. At 200ppm it looks like glorious *mud* to reflected light, but put a strong light behind it and you'll see that it's still clear. I am unfamiliar with zeta potential so would welcome your observations on that. Reid James-Osbourne: Holmes, Are the very high concentrations made electolytically? If they are made by precipitation, the Zeta potential may be very different. -- The silver-list is a moderated forum for discussion of colloidal silver.
