Yes. We no long have the Perkin Elmer Spectrophotometer in the lab, so we now use a simple test kit available from www.nitrate.com. The product is called the Nitrate Test Kit (NTK) and is available for testing in two ranges: The standard range is 0.5 to 10.0 ppm The low range is 0.05 to 1.0 ppm For $35 you get a test kit that will test 25 samples. frank key -- The silver-list is a moderated forum for discussion of colloidal silver.
