I had it checked at a laboratory using a ZetaSizer Version PCS. The particle sizes and concentration (ppm) of colloidal silver are at the bottom end of this machine's capability. I have had 30VDC CS checked with scanning and transmission electron microscopes. But not the HVAC CS. I'm going to make HVAC and 30VDC CS from the same water and compare them with a transmission e. microscope. I will also have a look at the distilled, deionized water I'm using just to see what lurks in there. I have just thought about my HVAC results yesterday. I used distilled water from a different lab. I am now wondering if the particle size was not so small that the ZetaSizer did not even measure them, but measured impurities in the water?! I'm actually hoping that this is the case. I use a home made HVAC unit. It runs at 12000 volt ac 50 Hz and has a max current rating of 30 mA. My electrode setup is identical to Bruce Marx's. Not an easy business to measure CS for its ppm and particle size. My time is a bit limited right now, but when I have new results I'll post them. I quite like the HVAC process. It is very clean and the hardware commands respect! I'm hoping to make HVAC CS that is on the same spec that Bruce Marx claims. Why don't you buy some of his CS and have it checked with e. microscope and ICP? I feel that if his machine makes what he claims, it is a must buy.
