Particle surface area is the property of a colloid that translates directly to the ability of the colloid to react with its environment. Effectiveness of colloids is predicated on exposing the largest possible surface area of the metal particles to the areas of interest. The importance of colloid particle surface area cannot be over emphasized. It is the single most important attribute for determining how effectively the colloidal particles will interact with their environment inside the human body.

In his booklet “Silver Colloids”, Professor Ronald Gibbs wrote: “The size of the particles in the colloidal silver suspensions we use for health purposes is very important. Particle size controls the surface area and therefore the effectiveness of the colloidal silver suspension.”

In this context, effectiveness is defined as the ability of the colloid to interact with its environment, just as in the world of chemistry, where surface area determines how well substances react with one another. For a more complete discussion of the rationale for comparing colloidal silver products using particle surface area as a single valued metric see: Comparing Colloidal Silver Products.

The table below shows the particle surface area values for various colloidal silver products for comparative purposes. A home hobbyist colloidal silver generator is displayed on the first line of the table to show a representative sample of home made ionic silver produced using the electrolysis  process.

Particle Surface Area is expressed in square centimeters per milliliter of colloidal solution (cm²/ml).
Efficiency Index expresses effective surface area per unit of concentration (ppm) of silver.
