Tim & Jim, An ion is a charged particle or molecule, it really has no relationship to size. Here are a couple of definitions: Atoms vs. Ions. Atoms are neutral; they contain the same number of protons as electrons. By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion. ion Chemistry an atom, radical, or molecule that has gained or lost one or more electrons and thus acquired a net negative or positive charge. In electrolysis, positive ions (cations) travel to the cathode, while negative ions (anions) travel to the anode. (Coined by Michael Faraday, from a Greek form meaning going.) This term has been confused in the colloidal silver world, mainly due a 'technical note' found at the CSPRO web site, I suspect. AC generators, like DC generators can produce a range of particle size, no doubt, but AC generators cannot generate ionic particles in any meaningful quantities. CSPRO make a point of this themselves and have posted test results as proof. In other words, ionic suspensions will give a reading of some potential on a TDS meter (when properly callibrated - see note at end.) whilst elemental, or non-ionic suspensions will not as they have no charge. Ionic CS has a much greater biological action than elemental CS and some say this positive charge accounts for its effectiveness in treating human aliments. I dont know this for sure, and non-ionic CS has helped many, by all accounts. Bruce K Stenulson has further discussion on this point on his web site: http://web.idirect.com/~showcase/althealth Just a short note to a large topic: measurement using a TDS meter. A TDS meter is a cousin to the Ion Selective Electrode (ISE which I use, and which is a damn sight more expensive, unfortunately), but when measuring a solution containing only one ionic species, it does the same job. It may be of interest, then to note the procedure for calibrating an ISE. Aquious solutions of known concentration are obtained, covering a range of one or two decades, I used silver nitrate AgNO3 at 50 PPM and 5 PPM ( I added 25 PPM for good measure) as Ag. Any chemical lab can do this for you at little cost for 1L of each. Be sure to shake before use. (Dont drink this, its toxic and you'll turn blue, pun intended) If your meter has enough adjustment then you will able to obtain a direct readout of concentration in PPM of Ag+ (if thats whats in your colloid). If there is not enough adjustment then you will need to draw a graph, PPM on one axis, readout on the other. If, in the unlikely event, this does not prove to be a straight line then you may need to use semilog paper (as I do) with the readout on the log axis. Try for log paper with as few decades as possible which is easier to read. Confirm your results occasionally at a lab by Atomic Adsorption (AA). This will measure the total silver content in mg/L (which as luck would have it is almost equal to PPM when measuring Ag in water). The results will vary a little from your measurements due either to some percentage of elemental particles (non-ionic) in the sample, or Ag ions which have lost more than one electron Ag++, Ag+++, which carry a higher positive charge.
