Hi, I see some discrepance in the ppm definitions, I do not knw what is the truth...until now. Look at the following text from www.elixa.com/silver/zanesize.htm and even if I admit the second version to be truth, then, I really miss the ppm importance, it seems to be vague if considering all aspects of the statement
...The statement 'less is more' is often made when referring to colloidal silver and colloidal technology in general. What this means is that the number of silver particles determines the quality and effectiveness of colloidal silver, NOT simply the concentration. The term 'ppm' or 'parts per million' is confusing because it is not referring to the number of parts or particles, it is actually a different way to express total weight or total amount of silver. Since a colloidal product can have particles ranging in size from 1n to100n, it is difficult to judge the quality of a product by simply knowing the ppm. For example, a product with a concentration of 5 ppm with an average particle size of 5n would actually have more silver particles than another product of 25ppm with an average size of 50n and thus be safer and more effective. -- The Silver List is a moderated forum for discussing Colloidal Silver.
