David,
PPM refers to mg of silver {in total} per litre of water as established under
laboratory analysis does it not?
If discussing - "PPM of dissolved silver ions" - then that would be referred to
as the 'Soluble Ag' component or content.
PPM content would be the total amount of Ag present in both ionic and
particulate form in that solution would it not?
