Hi Mike, You're beating a dead horse when you say it would be good "to find out how to make stable high ppm cs" We already know how. Use low current density, distilled water, current limiting and water movement. We've been doing it for years.
We calibrate our generators to produce at least 20 PPM at the "HIGH" setting. The CS never yellows at that strength. I made some using the SG7 almost 3 years ago at 45 PPM and it is still clear and colorless. We use DW from several supermarket chains and also have a Barnstead 1 gallon/hour still. I have never noticed any difference in the end product from using different brands. The only difference is in the time it takes to get up to speed at startup. It seems to me that large surface area and low current density combined with water movement is the best way to make a good product. I'm convinced that stirring is a key to making a good end product. As far as wire versus flat electrodes I prefer more surface area and that is more easily gotten with sheet silver. I'm not convinced a bit that the ions are released from the edges only. With water movement I think the edge effect is minimized and the whole surface comes into play. We calibrate every SG7 by making a batch and use three PWT meters to get an average reading. The meters are quite reliable and agree quite closely to actual AA readings. Of course you have to use them properly. Since our generators produce about 85% ionic, a correction has to be applied. We add 20% to the reading to get total silver content. If you measure right after shutoff, the reading is fairly close to actual total silver because it is mostly ionic. After sitting for 24 hours some of the ions form colloids, the CS becomes stabilized and the correction factor then comes into play. As far as using a salt test, I'm not even going to consider it. It's like saying "how high is up?" There's too much room for conjecture and personal bias. Just use a meter..... I cannot believe an engineer would use such a subjective test as using salt when a meter would give an accurate reading.
