For example, if you have a CDS concentration of 3000 PPM and you want to prepare a solution of 30 PPM, how many ml of the 3000 PPM solution will you need to achieve the desired 30 PPM final concentration?”
Initial CDS concentration (PPM)

Desired Final concentration (PPM)

Target Volume (ML)

You need 10 ML of CDS (3000 PPM) into (1000 ML) of water to have a (30 PPM) solution
