Re: Which kill pathogens - silver ions or silver particles?
Hello Tony,
That is an excellent test however let's look at the results and see if we can put them into easily understood terms.
First of all, the term ion means a particle that is electrically charged. When you pass electricity through water and in the process a silver electrode dissolves and goes into solution, you are forming ions.
When you use a high voltage AC process, ions are formed. When you use a low voltage DC process, ions are formed.
Now let's look at what a colloid is. A colloid is formed by the suspension of solid particles in a liquid. The particles are small enough to be kept in constant motion by the molecular movement of the suspending medium and they do not settle out of suspension under the action of gravity alone.
This means that all
Colloidal Silver that is produced using electrical currents is both ionic and colloidal.
The question is better stated as which is better a solution having a greater concentration of ions or particles? [smile icon]
OK, back to the test results.
The test is between Mesosilver and Sovereign Silver. The Mesosilver is at a concentration of 20 mg of silver per liter and the Sovereign Silver is half that at 10 mg of silver per liter.
This brings up the question... If the Mesosilver was further diluted down to the same strength as the Sovereign Silver, would the results still work out the same...?
E. coli was challenged by both these products and they both had some effect on killing it. The solution that was twice as strong eventually killed all of it. The half strength solution reduced, but did not totally kill off the E. coli.
Looking at the 2 hour results we find that Mesosilver was able to reduce the E. coli by around 15.8 times (30 million colony forming units down to 1.9 million CFU). The 2 hour results for Sovereign Silver showed a reduction of about 9.7 times (30 million CFU down to 3.1 million CFU).
Considering the Sovereign Silver solution is only half as strong as the Mesosilver solution, it made a pretty good showing for itself.
At 5 hours the Mesosilver solution was able to reduce the E. coli by around 56.6 times (30 million CFU down to 0.53 million CFU). The Sovereign Silver was only able to reduce the E. coli by about 23 times (30 million CFU down to 1.3 million CFU) or only about half that of the other solution that is twice as strong.
Isn't that amazing. The solution that is half as strong is only half as effective at killing E. coli over 5 hours...
At 24 hours, the 20 PPM solution had effectively killed off the E. coli while the 10 PPM solution was only showing a reduction of 230 times (30 million CFU down to 0.13 million CFU).
While I agree with their summary, I think they should have extended the testing time of the Sovereign Silver test to 48 hours to see if the half strength solution takes twice as long to kill off E. coli.
The bottom line is that both products are effective, but the higher concentration solution is more effective and works faster than a solution that is half the strength.
Is it possible that high voltage AC commercial production produces a product with more consistent particle size and purity? Yes, of course.
Home production can be done on a very primitive scale, however, with the investment in some testing equipment, and closely adhering to step by step processes, home production can produce a very good product.
There are many anecdotal stories of people having success with home made
Colloidal Silver .
The bottom line is that all the HIGH QUALITY products work, both commercial produced and home made.
