Hello there whoever you are, I do PPM testing for others using a spectrophotometer. The cost is $7.50 for the first sample and $5.00 for each additionalsample in the same shipment.

I've been told that with 14 gague wire, at a 72 degree water temperature, using no salt solution and using distilled water that I can make a 5 PPM 8-ounce glass in 22.5 minutes. Can someone direct me to a lab where I can get it tested and see how many PPM i am actually making? And do you know what it costs?
