: RE: CSMeasuring CS with a spectrophotometer or colorimeter
Thanks Marshall,
The pictures and plots are very informative. I believe you are right
about trying to measure ppm without digesting the silver won't work.
Your explanation has helped tremendously in understanding the theory and
operation
I tried posting this once but if it posted it did not echo back to me.
Jim,
Actually I got interested in this after two posters here expressed an interest
in lab testing of their CS. At least one using HVAC. Curious of what lab
testing costs, I looked around for labs. Frank Keys appears the

A spec turns a sample into a plasma and measures refracted light shown
through it at a given frequency.
A colorometer uses a pre calibrated chemical reaction pillow specific
to silver and compares colors the solution turns with the chemical reaction.

Thanks Marshall,
That helps. The info online relative to colorimeters does mention
digesting substances but I was unclear on how that might apply

Re.: picking the right frequency,
I'm glad you brought
