| Effectiveness of a colloid is determined by the particle surface area making it the single most important metric for comparing colloids. |
- This table is presented in ascending order of particle surface area (column 2) to provide an easy means for direct comparison among the various properties associated with particle surface area. Data from the product reports is compiled into a table so the reader can compare products based on costs and particle surface area.
- Product Name: These are the colloidal silver products listed in the Product Reports. Click on the product name in the table below for the complete lab analysis.
- Particle Surface Area: In the table below, Column 2 (Particle Surface Area) provides the best means for a direct comparison of the various products. Column 2 (cm 2/mL) is particle surface area in square cm per mL from the Product Report.
- Efficiency Index: Column 3 Effective surface area per unit of concentration. Particle Surface Area (cm2/mL) per ppm X 1000. This value relates how efficiently surface area is generated per unit of concentration (ppm).
- Comparing Cost: Column 5 (Cents/cm2) is the Price in Cents per square cm of particle surface area.
Column 7 (cm2/$) is square cm of particle surface area per dollar of cost.
- Comparing Quantity: Column 6 (Normalized mL) shows the quantity of the colloid in mL required to provide a constant particle surface area. The values are normalized.

Higher values are better. Lower values are better. Notes: Col. 1 Product Name and concentration in parts-per-million (ppm) on label.
Col. 2 Particle surface area= value from lab report.
Col. 3 Efficiency Index = Divide column 2 by total ppm value from the lab report and multiply by 1000.
Col. 4 Price Cents/mL = Divide product price ($/oz) by 29.5734 and multiply by 100.
Col. 5 Price Cents/cm2 = Divide 1 by column 2 and multiply by column 4.
Col. 6 mL of product required for a constant particle surface area.
Normalized value is calculated by dividing the largest column 2 value (104.7) by column 2.
Col. 7 cm2/$ = Divide 1 by column 5 and multiply by 100.
