Silver
Colloidal silver concentration was 55% of expected, so manufacturer reported value of 3.2% was in error
Calculated silver ion concentration vs measured
If measured lower than calculated,
indicates silver sorption to
glassware, etc
~ 26% sorption of colloidal silver and 57% ion sorption indicated
77 % of the colloidal silver was <0.22 um in size
