Gaston, I tried bubbling with first with air and then argon. I found in using air that I was seeing a definite Tyndall Beam (TE for Alison) with many sparkles, which is not acceptable in my product. Argon was better, but too expensive, so I only use that as a pressure source for my filter (0.2um so that I can claim filter sterilisation). I find a slow mechanical or thermal stirring to result in a perfectly clear product with no TE. The selection of a very small current density is the secret of fine CS, and my small commercial generators use this to good effect, generating 15ppm in 500mls in about 2.5 hrs with no stirring required (however I do recommend stirring by hand two or three times during the run).
But to be honest, I have not compared the actual silver concentration vs. conductivity of bubbled and stirred CS, which is why I only suggested an increase in conductivity due to CO2 inclusion, which never the less I believe to highly likely.
