Ivan: Yes I received your 9-29-post great.
Regards to NZ. I lived near Wellington (Paikakariki and Paraparaumu I think)
from 1942-43. US Marine - 2d Division. Loved your country and your people.

Hi Christian,
Southern Hemisphere rules isn't it.
Bruce,
Awesome website you have there, probably the most informative I have
seen. In deed it is because of your technical discussion page that I am here
on the list!
I find myself echoing your findings, I feel we have travelled similar
research paths, although you are obviously a much nicer person than I
(CSPro).
I am using a current limited system myself, I also use voltage to
regulate current, I have a very versatile system. Max current <10mA max
voltage 24V .I filter at 0.2micron absolute with a standard filter in a
housing fabricated by moi in 316 S/S pressurised flow provided by Argon gas.
I do 20L per batch and anything that can speed up the process without
compromising quality is in order.
Bruce, I very much look forward to discussing CS production etc with you
et all in the future.
Hello Bob, and thankyou,
Yes I am in the position to do legitimate testing in every way but
financially. This costs big bucks, ... So little by little shall we proceed.
I must say that Vasivi (head of microbiology Amdel labs N.Z.) originally
planned a series of challenge tests but after a review of previous
literature she decided that this was pointless as CS inhibits every microbe
etc. Instead, we decided to jump straight to concentration limit testing (I
cant remember the technical term).
As to the testing already done unfortunately the scanned results run to
14meg per page and my ocr prog cant resolve them. You will have to accept
this summary for now.
Two batches were tested results same for both, except for mg/L (PPM in
water) this was so that I could verify my ion specific electrode (ISE)
readings against their atomic absorption (AA) tests for concentration. Batch
125 26mg/L and batch 126 20mg/L.
Bioburden Testing and Validation of Test Methods to Demonstrate that the
Test Specimen (Colloidal Silver) to which they are applied do not ,
themselves, inhibit the multiplication under the test conditions, of
microorganisms that may be present as per USP 23-1995, CTFAA NOV. 1989, BP
1998.... In other words the study was carried out to determine that the
media and methods used for testing the colloidal silver were appropriate for
the specific sample being tested in order that any viable pathogenic or
non-pathogenic microorganisms present in the sample were able to be
recovered.
Diluted samples of product were inoculated with separate viable cultures
of Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa,
Salmonella and Candida albicans.
Validation of test media - Pathogen Screen was confirmed
Product Validation and Sample Results - Pathogen Screen
Demonstrate that the test sample did not have any inhibitory effect on
the multiplication of the inoculated pathogenic microorganisms under the
test conditions as per USP23 1995 and CTFAA 1989
Both batches of colloidal silver solutions tested negative for all five
pathogenic microorganisms.
Validation of the Test Method - Effectiveness of Culture Media and
Validity of the Counting Method in the presence and absence of the product
as per BP (1998) Appendix XV1B-A243 was confirmed.
The two test samples were found free from both bacteria and fungi.
What this all means is: that the testing method is able to culture and
recover any pathogens fungus or yeast which may be in the CS samples, which
we all know could not possibly survive in CS anyway.... But these one off
(thank goodness) validation test now allow any batch to be certified free of
nasties by independent analysis, which I feel is important if I am to market
CS and my customers are to have confidence in it. And also, we now have the
foundation for investigating properly the germicidal properties of CS and
document its potential uses. Whew!
Also, these test results (not supposed to be reproduced except in full)
if presented by someone to some other lab, should allow this step in a
testing regime to be bypassed.
Next set of results should be much more interesting. Watch this space!
Thank you Paul,
Yes you are quite right, if it works it cant be bad, and I did jump in
boots and all. For that I am sorry. Although in my defence I didn't remark
on CSPro's effectiveness as much as their marketing technique,
scare-mongering, and scientific gobbledegook (oops there I again). Its
possible that their system actually vitalises water, something that I have
an interest in pursuing myself given time.As you may recognise by now my
marketing technique is slightly different, I figure I should practice what I
preach and reckon if everybody did that, well...
I look forward reading of your impressions of the difference between
LVDC and HVAC CS
By the way, spring is emerging between the squalls down here and things
are looking up.
Hi Deb,
This is so sudden.
Yes, come to NZ. Rachael my five year old (on Wednesday) is really
looking forward to meeting you. Can you cook? ; )
Seriously, if you or any lister wants to visit that would be great!
Well off to bed now. Best wishes to you all.
Ivan
