Firstly, a correction if I may, that 'colloid' determination I
mentioned from material I've read states *under* 1 micron, not *over*
Marshall, and I get the impression that this is a generalisation for
classifying what constitutes a 'colloid' in the field of
chemistry. Using this information, as I do, then finding out the size
a solid particle will pass through the gut wall, finding out the size
of the smallest capillary in the body, finding out the what is the
largest size which will pass through the blood brain barrier etc etc,
this is what I go by in making my determinations regarding quality of
solution and it's efficacy. Flawed...? well, praps it may be, but
it's the best a 'non chemistry' brain can go by.
The total AG was determined by acidifying using HNO3.
The ionic componant specifically is not stated, it just states
'soluble Ag', which I assumed to be the ionic componant. But as I
think I said earlier, this would probly include a percentage
of particles SMALLER than .45 microns which DID pass through that
filter, in which case I would imagine the particle content will
actually be HIGHER...Yes/No?
I would have to know the test that was run to know if the answer is yes
or no. If it was run by chromophotometry then the answer would be no.
If using a TDS type measurement, then once again it would be no.
Then it states "Solids (filtered using .45 micron paper)" = 5.0mg/l.
These would be the particles which are LARGER than .45 microns, and
who knows how many...? due to agglomeration during filtering process.
'That does imply that there were quite a bit of large particles present.
Then "theoretical insoluble Ag content" of 11.5mg/l.
I am guessing that they got this result by assuming some type of size
distribution, and using the 5.0 above .45 with a max of 1 micron to
determine how much was below .45. for instance 2/4.5 = 11.1 which is
pretty close using a linear size distribution.
In the result sheet it states, "Analysed using AAS using AgHNO3 STDS".
That's all I can tell you cos that's all I know. If I understood what
testing procedures would be SPECIFICALLY required then praps I could
have been more SPECIFIC with my list of testing questions. I did ask
for particle sizing but they were unable to do that due to specific
equipment required, of which they don't have.
They calculated %ionic/%particulate from these procedures being 51/49,
in this particular sample.
Well, with the large number or large particles, and the research I did
yesterday on ratio vs concentration I suspect that this sample was 30
ppm or higher and might account for the high colloid content.
