Hi Bob,

You ask, if this is a way to make small particle CS.  It is a way to
make smaller particles of less than optimal CS I suppose as reported in
Feb. TEM micrographs would be nice, but I can't afford them.

What interests me is why the concentration has gone down in both your
and Brooks reported tests. Especially as the tests I reported showed an
increase in concentration.

I wonder if you are both using the same test procedure, and what it is?
Could the H2O2 be interfering with the reagent in some way?

I am using an ISE as you know.

Ivan
