Mike, With all due respects to your magnificient calculations, but I will take the readings of my spectrophotometer every time. This is a commercial test set-up, and it i what the plating industry uses to measure the silver in the wash water.
As I said at 3 hrs. the PPM was 8.58, and 50 minutes later it was 39.6. And that is no BULL. The test is color metric and the difference is great. To me your salt test is not worth "a pinch of salt." Sorry, but there are two generally use methodes for measuring ionic silver. the spectrophotometer and the ISE, and they agree. I have crossed checked with four other sources and I know that what I read is correct. Send me a sample of your material I would like to measure it.
