Dan,
Thank you very much for attaching Trem´s post. It definitely more than
answers my question concerning the purity of silver to be used.

I am attaching a copy of a post by Trem concerning the question:
Hey Trem, do you guys have .9999 silver electrodes available? Just
curious. I see you only offer .999 on the web.

Hi Ken,
No we don't and for a couple of good reasons.
Here' an excerpt from an article on our website written by Peter
Lindemann.
"Purity of Silver"
The quality of your finished product depends entirely on the purity of the
water you start with and the purity of the silver you start with. Most of
the current literature suggests that only 99.9999% pure silver can be used.
Most home brew systems use 99.9% pure silver. So, what is the
difference?
To find out, I contacted Academy Metals, a company in Albuquerque, New
Mexico, that produces commercial silver. The total allowable impurities in
99.9% (.999 fine) silver is 1000 ppm or 1 part in 1000. These impurities
and their maximums are
1) Copper, 800 ppm,
2) 2) Lead, 250 ppm,
3) 3) Iron, 200 ppm, and
4) 4) Bismuth, 10 ppm.
This product is readily available in wire form and costs about $3.00 above
the market (spot) price of silver. When this product is used to make
electro-colloidal silver at a concentration of 5 ppm, the total impurities
from the silver drop to 4 ppb (parts per billion) copper, 1.25 ppb lead, 1
ppb iron, .05 ppb bismuth. With all allowable impurities at these low
levels, there is a reasonable argument for not being concerned.
Still, sometimes small things make a big difference. 99.99% silver (.9999
fine) has total allowable impurities of 100 ppm of the same metals in the
same ratios, and costs (in wire form) between $50-$90 above the spot price
of silver. 99.999% silver (.99999 fine) has total allowable impurities of
10 ppm, and in wire form costs about $250 above the spot price. 99.9999%
silver, in wire form, costs more than gold and is very difficult to find
commercially.
In one sample of 10 ppm colloidal silver we sent out for total analysis
(made with 99.9% silver electrodes), the primary impurities found were:
1) Sodium, 470 ppb,
2) Calcium, 260 ppb,
3) Manganese, 70 ppb,
4) Potassium, 50 ppb, and
5) Magnesium, 24 ppb.
Since none of these impurities could have come from the silver, it suggests
that the purity of the water should be of greater concern to the person
making their own colloidal silver, than spending extra money on purer
silver."
As you can see, there are probably more impurities in the water you use
than in the electrodes. And of course the 1 part in 1000 impurity is
usually copper and that's not harmful.
It's just not an issue.
I hope this helps you.
