Hello all, My Ultra Pro and my water produce about 7 PPM in 150 minutes. Yield is strongly influenced by small variations in start water PPM (conductivity). Even .5 PPM difference has quite an effect.
I like Bruce's units very much. He has been very helpful in trying to solve the low yield problem, but we are both stumped. I trust his data. I think the problem lies with my water, which is Santa Fe city water through a RO and a Still, with Carbon for the light organics. There are so many touchy variables that I am not monitoring that hesitate to make definitive statements. I am measuring mg/L with a well calibrated spectroscope; it comes up spot-on measuring a 4 PPM solution of ACS grade AgNO3. My dilution should be 4.0. The scope, using the Hach reagent set, minus digestion, reads 4.0. I have tested the secondary voltage with a high voltage probe, Fluke 87 meter, and an oscilloscope. That was just to check the waveform when using the generator with a not-quite-true-sine-wave inverter, but it read nominally the same as the VM. The voltage is OK. 4K and some change each side of the center tapped tran. I measure water TDS/conductivity with a Sprite 6000 meter. My PPM results correlate well with both Bruce's Spec. and Bob Berger's. The quality of the silver produced is superb; I am of the "small is better" school---at least as far is silver is concerned---and sol produced by this process comes up between 0.5 and 9.x nm when viewed with a TEM. Not mine yet. 300 bucks per hour is tough on my R&D budget. I think I would rather drink a larger volume of 5 PPM ultrafine Ag than less volume of a higher concentration unless it has been proven to be very small particle. Remember, Brooks B. prefers 5 PPM. I think there is a range of relationships between particle size and concentration. It may not be possible with today's techniques or any technique at all---for that matter---to make high PPM silver by any method and have very small particles. Laws of nature and nature's God. Those of you who have not perused a text on colloidal science have no idea how touchy this stuff is. I would have to go back to school for about 3 years full-time to follow the math, maybe. I don't have time to review my production records now, if you would like, I will send you some of the data when I get a breather. Let me know. Happy brewing...

James Osbourne, Holmes >> Well, I guess, all I can go on is Bruce's (Csprosystem's) inferance that he has researched the unit and tested batches that come from it. I really only have his word and reputation for it. I have not tested any of the product from the unit - only used it. No one here that I can remember has ever disputed his claims, about the units that he sells. Now maybe I missed something is the 9 months I was away from the list. As far as I know, Bruce has a tendancy to understate something rather than overstate it. How do you feel about his units and production figures as marked below? The CS it produces works wonderfully.
