A brix meter I believe will do the same thing. A relatively inexpensive hand held refractometer. should be able to give you reliable ppm for what ever is in solution. A search for "brix refractometer" will give several companies that make them plus contacts for technical support. Also need to consider the life in the water as I believe this is just as important as the silver. (related to ozonation and spring water) I have attempted to contact "Water Research Institute" in blue hills maine, 207-374-2384. They supposedly have a system for measuring the biological activity of water and mineral salts in water. They are apparently on vacation right now. will post to list as soon as I have any information. There is a book called " The NEW AGRICULTURE" circa 1930 Available from the: Biodynamic Gardening Association PO Box 550 Kimberton, PA 19442 610-935-7797 that covers some of the background of the system. There is a copy in a library about 35 minutes from here, but they are in the process of moving and I wont be able to get a copy for a few weeks. Again will post to list as soon as I have more info. A medline search for "photodynamic therapy" will give you all sorts of references to medical research using photosensitizing agents and the treatment of cancer. Interestingly enough the major compound that acts as a photo sensitizer is a natural constituent of blood (porphyrin). Its method of action is related to hydrogen peroxide, oxygen stress and hyperthermia, Lot of clues if you have the time and patience to wade through it.
