Concentration

How is everyone determining concentration per mL? I see some bottles of gold saying concentration per mL of gold in it. Since we are making it I want to be as close to them as possible from the sellers.

When making colloidal gold from gold chloride, the gold chloride is measured so we know exactly how much gold is in the final solution.  If making colloidal gold by electrolysis, the gold content is estimated by the color depth.

A milliliter of gold chloride solution from Salt Lake Metals makes 250 milliliters of 40 ppm colloidal gold.
