There are three distinctly different types of silver that are labeled and sold on the market as “colloidal silver products” they are ionic silver, silver protein, and true colloidal silver. Consumers seeking true colloidal silver are often at a disadvantage because each of these products represents themselves as colloidal silver.
Commercial Colloidal Silver Product Reports provide detailed laboratory analysis of colloidal products. Tests are performed by the Colloidal Science Laboratory, Inc.(CSL) using a uniform set of analytical measurements. The information contained in these reports is provided as a service to educate consumers and is not intended to promote any particular product. CSL does not receive funding for its work from manufacturers, and anyone can submit a product for testing.
Scientific product testing performed by CSL is an unbiased examination of the physical properties of colloids using the best scientific methods and equipment available. The equipment used to perform the analyses is calibrated to standards traceable to the National Institute of Standards & Technology, and the personnel performing the measurements are skilled in the use of the equipment.
The instruments used to perform the tests are described in detail and the test methods are fully revealed so that the entire suite of product tests can be duplicated by others. See Determining Properties for technical details about how the laboratory analysis is performed. Detailed lab analysis for the products shown in the table is available by clicking on the product name in the table.
Before exploring the reports, charts, graphs, and details of the tests, it is important to have a basic understanding of the three types of products that are marketed as Colloidal Silver products.
