Ole Bob, With all due respects for your great contribution to the understanding of CS, you are wrong on this question. There are several good reasons that I know the concentrated CS we use is not the nitrate. Firstly, I make this myself using only the de-ionized water and the silver rods. There is absolutely no other material in the process.
Could it be that a missing link in your understanding is the polarity reversal? I avoid the current runaway that leads to oxidation by switching poles every minute. A reason that I know that the Mexican CSproducts, Microdyn and Biopur are NOT silver nitrate is that if they were they wouldn't work in the saturation of our water purifiers. As with our collaborators in Nicaragua, Potters for Peace, we saturate our earthenware purifiers with these Mexican CS products, with good results. If Biopur and Microdyn were silver nitrate the silver wouldn't lodge in the purifier matrix. It would get washed out the very first time water was put through the purifier. The fact that numerous lab tests have proven that the the purifier is 100% effective at killing pathogens is proof that silver is in there. Note: the purifier is about 80% effective when the CS is NOT used. As I've said in a previous posting, the concentrated CS generator I use was made by educate-yourself.org. The folks there have told me that to make CS that's more concentrated than the ~170ppm we get with four hours, additional time is what is needed. So, for example, if you want ~500ppm you would operate the generator for twelve hours. You and others on this list have variously stated that it is impossible to make CS with concentration higher than about 30 to 50ppm. On the other hand you've recently tested a CS that was about 100ppm. (That it was supposed to have been 500ppm suggests to me that the manufacturer had a bit of the current runaway, but not enough to see that the solution had gone gray.) Doesn't this give you a proof that the higher concentrations are indeed possible? I think that the doubting Thomases here should put on there thinking caps, and imagine that there are ways of making CS other than the ones we know and love. Our resident expert Roger Altman has been gracious enough to provide us with equations in physical chemistry that prove that the higher concentrations are indeed possible. I am concerned that if we continue being uninformed on this process we run the risk of turning away those would-be entrepreneurs who could do a great service by providing concentrated CS in poor countries. The reality of Microdyn and Biopur needs desperately to be replicated in other countries.

They are buying some kind of compound. It is not Electro-colloid.!!! I have never seen an analysis of the Mexican products, but having lived in the tropics for 9 years I wouldn't trust that stuff on bet.
