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.
