Elements Of True Colloidal Silver

By Raymond Petros

The term true colloidal silver is used to describe a silver colloid wherein the silver content is composed of silver nanoparticles in preponderance as compared to silver ions.

The Colloidal Science laboratory is remembered as giving the substance its legal name which it did back in the early 90s.

There is a certain level of the substance which is known as true colloidal silver. A batch of colloidal silver that has a very high concentration of nanoparticles is known as true colloidal silver.

It is only when the nanoparticle content is in majority over the silver ions that colloidal silver gains the above mentioned title.

Measuring true colloidal silver

A technique known as atomic emission spectroscopy can be applied to determine the concentration of silver in a batch of CS. The unit of measurement used to denote the silver content is known as parts per million.

PPM gives us the exact ratio of silver to the liquid in which it is suspended. If a reading shows nPPM it goes to show that the water content has n milligrams of silver content.

However, true colloidal silver has nothing to do with the total silver concentration. Rather the nanoparticle count is what makes this conclusion.

The concentration of silver does not in reality restrict the CS in any way. This is because so long as the nonparticles are in majority the liquid can still be true colloidal silver irrespective of its silver concentration.

Ionic silver products in general have a much lower percentage of nanoparticles when compared with true colloidal silver. This is why such products are simply referred to as ionic silver.

How to determine true colloidal silver

For checking the silver concentration as to whether or not it is true colloidal silver we need to count the nanoparticle concentration independently.

Majority of the silver concentration products are composed of both silver ions and nanoparticles. This is why a method to separate these two contents was developed.

The correct procedure for separating the silver nanoparticles from the silver ions came about after years of trial and error.

With the G-forces and time intervals required determined scientists could now easily separate the two components.

Dynamic light scattering techniques wherein which a powerful beam was made to pass through the silver concentration was the technique used for the procedure.

Individual photons from the nanoparticles could then be figured out.

Digital signal processing algorithms would then be used to process the reflected laser energy. This was a very important technique that was essential to determine the value of true colloidal silver.

With the two items separated, figuring out whether the liquid concentration is true colloidal silver or not becomes obvious.

When the nanoparticles count is observed to be more than 50% the concentration will be termed as true colloidal silver.

Unfortunately there is no way of determining whether a silver concentration is true colloidal silver apart from the extensive laboratory mentioned in brief above.

You will be able to find many colloidal silver products being promotd as true colloidal silver whereas in reality the producing company does not have any idea about nanoparticle percentage in their product. - 14130
