  All About TDS meters  

A TDS (Total Dissolved Solids) meter is an extremely handy addition to your colloidal silver kit. It measures the initial purity of commercial or home distilled water, and provides a useful guide to the final ionic PPM (Parts Per Million) of your colloidal silver. Its also very handy for testing the quality of your mains water, rain water or bore water.
This good quality meter features advanced microprocessor technology.
- Hold Function (saves measurements for convenient reading and recording).
- Auto-off function (shuts off automatically after 10 minutes to conserve batteries).
- The measurement range is from 0-9990 ppm. From 0-999 ppm the resolution is in increments of 1ppm. From 1000 to 9990 ppm, the resolution is in increments of 10ppm indicated by a blinking 'x10' image.
- Temperature gauge. 
- Includes a neat carrying case with belt clip.
- Uses just 2 button batteries, not 4 like the similarly priced blue Hanna TDS-1 and it has much bigger, easier to read numbers, and is easier to use than the Hanna meter too.

Note 1. All TDS meters measure the conductivity of dissolved charged Ag+ IONS only, then they convert that reading to an estimated PPM. They cannot detect or measure PARTICLES (colloids) as these are not actually dissolved and therefore they are non-conductive. In clear colloidal silver it is generally assumed that the IONIC component will constitute 85% to 95% of the TOTAL PPM. The PARTICLE component, even though it is not measurable by the TDS, would be an additional 5 to 15%. (That's assuming you started with pure water with a near zero reading). The Tyndall Effect described at the bottom of this page is the simple indicator of the presence of the colloidal particles.

Note 2. All TDS meters are factory calibrated to provide an estimated PPM for the most common dissolved ion, sodium chloride (salt), not colloidal silver. But salt is about twice as conductive as silver ions, so when using a TDS meter to estimate the ionic PPM of colloidal silver, the recommended practice is to multiply the reading on the meter by 2 to 2.5 times because it has actually taken at least twice as many silver ions to reach the level of conductivity indicated on the meter. So, for example, if the TDS meter says 6 then your actual ionic silver PPM is probably closer to 12 to 15 ppm. ALL TDS METERS work as described here! So if anyone tells you you can simply read a colloidal silver strength directly off the dial of a TDS meter, they dont know what they are talking about.

Note 3. TDS meters (and EC meters such as COM100 below) cannot distingish between silver ions and various other types of impurities, so to use them for measuring colloidal silver you must start with pure water.



  Colloidal silver  Imaginary 15 hours batch  
  The grey curved line indicates the Total PPM. The background color indicates the color of the water of this imaginary batch at that total PPM. The example brewing time here is 15 hours, but depending on variables such as water volume it could just as easily have been 1 hour.  
  The graph above plots the progress of an IMAGINARY batch of colloidal silver over a period of 15 hours. . It's just an imaginary batch I've constructed 'on paper' to illustrate a few points - including the point that there may be much more silver in the batch than what you might simply measure with a TDS meter. It should not be viewed as advice that every batch will go yellow from about 10 PPM or go dark grey at 80 PPM. (A real batch can go yellow from as low as 3ppm).
  A. The 5 hour mark. This would have been the perfect place to stop this imaginary brew. The TOTAL PPM (the grey line) is 15. The IONIC PPM (red) is about 13, a proven safe dose and very effective if you drink enough. And the PARTICLE PPM (black dots) is about 2. But the water is still nice and clear indicating that those particles are tiny. This would be very nice CS. Although this is an imaginary batch, most research seems to suggest that good quality CLEAR CS is usually about 85 - 95% ionic and 5 - 15% particles, so a TDS or EC meter that only measures the IONIC PPM can probably, by reasoning, provide a clue to the TOTAL PPM as long as the CS is CLEAR.

B. The saturation point. The saturation point is the limit at which water will continue to hold another substance (in this case silver ions) in solution, so in theory this is the highest ionic ppm that can be achieved. Above this point the ions will precipitate out of solution, form particles, aggregate into larger particles, and eventually, if the particles get big enough, fall out of suspension over a period of hours or years. In this imaginary brew the saturation point is about 24 ppm but it varies depending on factors such water quality and temperature. It's important to note however that tiny particles can begin to form and aggregate well below this saturation point - as indicated by the Tyndall Effect in a laser beam, or the yellow colour of the water. The presence of particles may in some instances prevent the batch from ever reaching its saturation point because particles continually draw ions out of solution.

Note about particles. Particles (the dotted black line) begin to form almost as soon as the power is switched on. The aim is to minimise the particle size. This is best done by using a combination of current control and stirring to create ions and particles slowly, and disperse them to low concentration zones where the conditions are less advantageous for particle aggregation. 


C. The 7 hour mark. The operator probably should have stopped this batch as soon as it developed a little bit of color. The TOTAL PPM (the grey line) is now about 30 but the water is starting to turn grey. The batch is near saturation point for IONIC silver so the particles are rapidly becoming more numerous and larger. It's borderline quality for drinking but its fine for topical use.

Note about colour. The colour change of the water is usually not as simple as a straight progression from clear to yellow to grey. Very often the water will go straight from clear to a very pale grey without any apparent yellow stage. But often that pale grey CS will turn yellow if you leave it overnight.

  D. This 'leveling out ' of the IONIC PPM (as illustrated by the red line) often leads at-home CS makers who use a TDS meter to think that the PPM of their colloidal silver is no longer increasing. In fact the TOTAL PPM is increasing rapidly. The process of electrolysis will continue to dissolve silver ions into the water as long as the power is on, but in our imaginary brew the saturation point of the CS has been reached so those silver ions can't stay in solution. They are coming out of solution and forming particles as fast as they are dissolving off the electrode. As particles become larger they develop a greater power to attract and draw ions out of solution. In fact they can sometimes attract the ions faster than the ions can be produced, resulting in a drop in IONIC PPM as illustrated by the red dashed line. This means that your TDS meter can show a drop in IONIC PPM even while you continue to brew.  
  E. At the 10 hour mark, the total PPM of this imaginary batch (the grey line) is about 45, but a TDS meter would only show 24 ppm because it can only measure the PPM of the IONIC silver (the red line). The effect of stirring and current control in a good quality generator is to delay the formation of particles for as long as possible, and to minimise their size when they do start to form.
  F. After 15 hours. The water is now almost black. This is CS for the garden or for making GEL thats the color of axle grease. (I have, and I quite like it). But I definately wouldn't drink it. Total PPM in this imaginary batch is 75 PPM but a real batch this color might be hundreds of PPM.

Yahoo Discussion Group - 4colloidalsilver (Previously colloidalsilver2).

Colloidal silver2 was the biggest and most active discussion group for CS on Yahoo. But it hadn't had an active moderator for years so Yahoo finally delisted it. So 4colloidalsilver has been started WITH a moderator to keep the spam out. Membership is small but should grow rapidly as CS2 members move over. Discussion here can be pretty robust.


Colloidal Science Laboratories.

Scientific information about silver colloids. This site is owned by a company that produces Mesosilver, a colloidal silver with a very high particle content, so it is highly biased in favor of 'particulate' colloidal silver. Nevertheless it is an outstanding site with informative FAQ's and explanations of scientific terminology. It also has an extensive list comparing commercially produced colloidal silver. (U.S. brands). Some are revealed to be little more than plain water. Important Note: The brochure offered on page 1 as a free download (Silver Colloids - Do they work?) is highly supportive of 'particulate' colloidal silver but it has a serious flaw. The author, Ron Gibbs, believed he was studying highly particulate colloidal silver, when in fact it was highly ionic.
This admission is only revealed on the site's FAQ's in a question concerning the colour of Mesosilver.

Quote from the silver-colloids site:

"Regarding the dark color of high particle surface area colloids"
Question: Dr. Ronald Gibbs booklet states that high-quality Colloidal Silver is colorless, but the highest particle surface area colloid in the tabulations is dark in color, why this discrepancy?

Answer: The material in Ron Gibbs book is slightly dated. Ron died in May 2000 and the book material was frozen about a year before. For example, the samples that Ron tested, some of which were made for him in the Colloidal Science Lab. Inc.(CSL) were believed by Ron to be at least 50% colloidal when in fact they were mostly ionic (typically 90%). The methods developed at CSL to determine ionic vs. particle concentration were just being developed at the time Ron wrote the book and so he was not fully informed about the ion/particle ratio of the test samples and consequently made some erroneous assumptions. Ron assumed the sample were at least 50% particles when they were only 10%. (So in fact Ron Gibbs was proving that IONIC silver works)


Where does it go when you drink it?

"The Altman Study. Colloidal Silver: Where does it go when you drink it and how long does it stay there? A study by Roger Altman". This research basically concluded that silver is eliminated from the body (mainly in urine) almost as fast as it is consumed. And, after ceasing to ingest, what little remained in the body would be 50% eliminated within 20 days and 100% eliminated within 100 days. "The completion of this study marks the first real step toward conclusive evidence that the risk of colloidal silver toxicity is negligible. It can be stated with extreme confidence that a body, under normal conditions, does not retain colloidal silver in bodily tissues in any form, especially if the daily colloidal silver consumption is 2 mg or less (more than twelve ounces [350 mls] of 5 ppm colloidal silver daily) for reasonable periods of time."

Proof that colloidal silver kills germs

Heres a list of over 100 medical, scientific and other credible documents that prove that silver has antimicrobial properties.

There are dozens studies that prove beyond doubt that colloidal silver kills germs in the laboratory. Here's just one such study, conducted by Brigham Young University. The results suggest 'ASAP Solution' is a broad spectrum antimicrobial agent. ASAP is good quality bottled 10 PPM and 22 PPM colloidal silver solution. 96.4% and 87.9% ionic respectively. (Silver Well CS is approx 87% ionic)

And here, The Oxford Journal of Antimicrobial Chemotherapy is in no doubt about the safety and killing power of silver... "The antimicrobial activity of small amounts of metal, known as oligodynamic action, has been known for a long time and is the basis for the development of many therapeutic agents... Recently, ionic silver substances have been resurging again in popularity. What makes silver unique in comparison with other antibiotics is the fact that it has no toxicity and carcinogenic activities."



More tests proving the germ killing power of colloidal silver

Link 8 above is a site that is very 'pro-particles', but this link shows the other side of the 'Particles vs Ions' coin. These studies suggest the ionic component of colloidal silver is more potent as a germ killer than the particle component. "Normally, when cs fails to kill a bacteria or virus, the problem can be solved by increasing the ionic strength. As Steve Quinto shows, a weak CS has little effect on bacteria, but increasing the strength kills 'em dead". (Quote from Mike Monett).

This following link takes you to a recent in-vitro study that specifically states it's the ions that kill the germs. This study was accepted by Pub Med, a service of the US National Library of Medicine. PubMed is considered a 'reliable source' for articles in Wikipedia.



Colloidal Silver Chemistry

Heres a pretty good theory of the chemistry of colloidal silver, and how it does what it does. Note the paragraph on silver compounds refers to potential problems created by using ordinary tap water, not distilled or demineralised water. Also note this very important phrase ''Ionic silver has the proven ability to cause DNA to dedifferentiate or revert back to stem cells''. You need to study that a little bit to really understand the possible implications.
