The distinctive feature of colloidal silver is the fact that it has more silver nanoparticles than it has silver ions.
It was back in the 90s that the title colloidal silver was designated for the product by the Colloidal Science Laboratory.
There is a certain standard 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 earns the above stated title.
True colloidal silver measurements
The precise silver content can be measured in parts per millions using a technique known as atomic emission spectroscopy.
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 solution has n milligrams of silver content.
As mentioned above true colloidal silver refers to the concentration of silver nanoparticles in the liquid and not the total silver concentration.
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.
The ionic silver products that you find in the market have a much lower nanoparticle content. This is the reason why they are being marketed as ionic silver and not colloidal 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 measure the nanoparticle concentration independently.
Since most silver concentration products had both nanoparticles and silver ions it was necessary to develop a means of separating the two.
Years of hard work, trial and error finally provided a viable method of doing so.
The breakthrough came when scientists discovered the exact G forces and time intervals at which the two liquids were to be separated.
Scientists were also able to determine the separation of the two liquids using dynamic light scattering techniques. A potent beam would be used to pass through the liquids.
This made it possible to count the nanoparticles and photons on their own.
The reflected laser energy would then be processed using digital signal processing algorithms. This was the finishing touch that provided the exact results.
Following this procedure it becomes obvious whether the liquid concentration is true colloidal silver or not.
When the nanoparticles count is observed to be more than 50% the concentration will be termed as true colloidal silver.
While the above mentioned technique does bring to light whether or not a particular liquid is true colloidal silver or not, the process is time consuming and costly with no real alternative at hand.
Many unverified colloidal silver products are being sold in the market as true colloidal silver products. However most of these products have not been checked using the above mentioned technique.
