Marshall, I used mutualcornell to test the 50 PPM made by my "ultra" generators. https://www.goldismoney2.com/threads/the-art-of-making-colloidal-silver-silver-ions-electrically-isolated-silver.61973/page-6 You can deduce the particulate versus ionic ratio by the results before and after the addition of nitric acid. Best regards, Arnold

I need an exact measurement of the total silver, but a percentage of colloid vs ionic would also be nice. Thanks, Marshall -- The Silver List is a moderated forum for discussing Colloidal Silver.
