Some of you might recall I had questioned the strength of my 500ppm CS. I 
sent it to Bob and seeing his post below reminded me I meant to post the 
results which are:

<<OBSERVATIONS:

CS is deep yellow in color. The colorant what ever it is, stains paper
instantly which does not happen  with a CS that turns yellow is applied
to white paper

The conductivity measured 754 uS.

The T.E. is very bright.

The concentration as measured with my Hach spectrophotometer using Hach
color metric chemical test kit # 22966-00 was 105.6  ppm.

I could not test it for nitrates as the colorant interferes with the
color scale.

When I was developing a the HVAC arc method I experienced conductances
in the 700 to 1000 range, but they always had unacceptable amounts of
NO3 (in the 40 to 80 ppm range)

Although his lingo is unfamiliar to me, the bottom line is the 500ppm is only 
105ppm. 
When I first purchased this CS many years ago, I thought 500ppm was the norm 
until I started seeing 10-12ppm. Then all sorts of questions came about. 
<< Helen;
  I have tested two samples from other sources that claimed to be 500ppm. One 
was
 64 ppm and the other was 104 ppm.
 I have very serious doubts that you have 400 ppm colloidal silver.
 As for IV EDTA chealation I have had it and it works great as a chemical roto
 rooter for the vewssel system.

Some time ago when I first found this list and had sent off my sample to be 
tested I ordered some other CS. In the interim, I had eaten lunch one day and 
within 45 started to get really ill (that'll teach me to eat my own cooking) 
I got vertigo, severe nausea, head ache...  I had food poisoning, been there, 
done that. I grabbed that NOW 105ppm CS and took about 1 - 2  T. Within 10 
minutes I was almost symptom free. I can't tell you how relieved I was, the 
last bout with food poisoning put me in the hospital, just gads of fun. 
So for the lurkers... IT WORKS!
