Robert et al, I test CS for concentration with my spectrophotometer. The cost $7.50 for the first sample and $5.00 for each additional sample in the shipment.
Why do you want something more than 16 ppm, when the in vitro testing show that 1 ppm is better than 10 or 20 ppm???? In fact in the Nethrlands a case where 20 to 40 PPB (that is pasts per billion ) cleaned up a greenhose of cucumber fungus. (personal knowledge). I make 2 gallons of 10 ppm in 10 hours that is sub-nm to 24 nm in size. Wht makes you think that yopu are making 16 ppm?
