-----Original Message----- From: Frank Key [mailto:fr...@strsoft.com] Sent: Wednesday, March 28, 2001 4:36 PM To: Silver List Subject: CS>Commercial Product Reports
Technical information on the physical properties of colloidal silver commercial products is available in a new section titled "Commercial Product Reports". These reports provide detailed laboratory analysis of the physical properties, and include: total silver ppm, ionic silver ppm, percent ionic, percent particles, conductivity, turbidity, particle size distribution plots for intensity and volume, zeta potential plots. There are now three products listed, other will be added on a time available basis. The product reports now available are: Silver Lightning Tonic Water "Wonder Water" Silver Fortified Water Sovereign Silver The reports can be viewed at: http://www.silver-colloids.com/Reports/reports.html Frank, before I begin my commentary on your "authoritative" analysis of cs products, I thought I'd just remind you of [what all of us can appreciate, objectively] the definition of a fanatic. It is: "one who has lost sight of his objective ....but redoubles his efforts." [attributed to an anonymous Frenchman] For it seems that you have lost sight of the purpose of all our efforts -- the baseline efficacy of CS materials, and how to get there. This principal issue is one you never address. I have to tell you: it is the primary something that drives our efforts here. I think we have a handle on that in our lab; we often do comparative bacteriology so as to make such determinations. I'm sure you will recall, even though you have ignored me, we have twice offered to include your 'ion-less' concoction in the analyses we do. But each time you demurred, first with some weak reply about your doing it at the? university, the results of which, BTW, we have never heard or seen....? And, then, you just ignored my offer. How many on this list do you think would refuse such an offer? Still, the list has heard nothing from you about how useful [or effective] your silver particles are.... We have been treated to lessons on your the adherence to science that are embodied in your efforts. But never anything about what it is all for.... Frank, Having spoken with one of the scientists at Malvern Instruments today, it was made quite clear to me that the Zetasizer is NOT intended for particle characterization, only size distribution and for "bulk analysis" at that! .....ie. for distribution of particles of greater size than those found in a fine colloid. The machine may be spec'd down to 2nm at the small end, but he [the scientist] was reluctant to say how near that end it can accurately get..... Furthermore, he opined that TEM is a very useful complement -- how did he put it? "a valuable supplement" -- to the Zetasizer, esp. for particle characterization AND measurement of nanometer sized particles, and for all such particles that are visible by TEM but may NOT be to a Zetasizer. The Malvern instrument does not present itself as for Particle Characterization. As happens often with colloids that contain very small particles, 'particulate' configurations that appear to be spherical 'semi-agglomerates' may present such a face to laser diffraction that they are taken for particles when, in fact, they are not! .... This in clear juxtaposition to the oceans of tiny particles that are just too small for the Zetasizer to even 'see'. Though the semi-agglomerates may be actually comprised of the same discrete particles that are similar to those circulating freely, the Zetasizer sees ONLY the semi-agglomerates and takes them for giant particles, while we see the discrete particles within them by TEM. Exceptionally fine colloids [and the micrographs of them, such as those on our website], are endowed with particles in the nanometer sized class, or less, But these don't even show up on your printout as part of the distribution curve! Because the Zetasizer cannot see them at all! So, then, the oceans of tiny particles that are characteristic of a fine colloid are the same that are seen in such spherical semi-agglomerates. That they are drawn together, upon close examination and yet remain distinct, still repelling each other ....is an interesting phenomenon. They appear only just able to resist the attractive force drawing them into such spherical configurations by so remaining distinct. But the Zetasizer cannot see or make this distinction. The Zetasizer cannot distinguish the discrete particles because they are too small for it, just like the oceans of free particles. So it says the distribution only includes the phantom image you are taking literally to mean they are particles of such and such size. Were these actual particles of the magnitude your machine describes, the 'solution' harboring them would have the characteristic colors appropriate to those large sizes -- namely yellow to red to green. As well, the Malvern scientist could not assure me absolutely that there is no magnetic energy created by the machine, and we already know that the finer the colloid, the more magnetic fields impact it..... I'm sorry, Frank, the analyses you present on your website -- of commercial products -- just doesn't 'cut it'. We've also looked at the other cs products you've "analysed", and find your similar FAILURES with them as well. And, really, if you reflect upon it, you just can't suggest there are micron-sized particles in those colloids! First of all, because you could almost see them with the naked eye, or at least with a laser -- as they would look like huge arc-lit sparklets in a laser beam. Which is patently not so! And there would also be color ....which there is not! Furthermore, I do not doubt that the CSPro product has been characterized by other TEM labs and is in possession of very different results than those you have tendered for the size and distribution of its particles. I'm sure the other 'analyses' will support my contention that there are alot of 2nm to 5nm particles in iot, NONE of which you show. And the giant particles your analysis describes -- 500nm -- do not exist except as the semi-agglomerates previously described -- which your machine cannot discern. Yes, there are particles in the 30 to 85nm range and they do show up, in quantity, and on your size distribution, but the overall analysis is faulty AND clearly lacking in comprehensiveness. With respect to the other cs product, your machine again misses the 2nm to 5nm particles that are very present. And the gross sizes you describe are once again those ephemeras, the semi-agglomerates.
