Application: Production of colloidal silver    What is colloidal silver?    Colloidal silver is made of extremely small silver particles. A silver  colloid  particles is about 60,000 times smaller than a red blood  cell. How long will the silver electrodes last?    For about 5,000 liters of Colloidal Silver (50 ppm). The electrodes  are  gradually dissolving. The silver wires are supplied with high  purity, ie consist of  99.99% silver, 2mm in diameter, 90 mm long,  hardened (do not bend so  easily).  What water should I use?  The purest colloidal silver is made with distilled water (purified  water from the  pharmacy), but also reverse osmosis filtered water will work.  The purer the  water, the smaller the current, the smaller the colloid particles, the greater its   surface area and their (antibacterial) effect. But many report excellent  effectiveness of even mere tap water.  Should I stirr or heat the water?  Heating increases the conductivity and thus the electrolysis process. Stirring  helps to avoid particle clumping in the conductive particle cloud between the  electrodes. Only distilled water should be heated (30-80° C), if time matters.  The miniSilver is powerful enough to give good results at room temperature.  How should I store colloidal silver?    Protect it from light, but don’t store it in the fridge. It is preferable to use freshly  produced silver.   Which mA (Amperage) should be used?  Another source states that the best colloidal silver is made by using an  electrode (anode) current  of 0.15 mA / cm2. The surface of the 2*90 mm rod  (as used with the miniSilver® colloidal silver generator) is 5.6 cm2, that is  around 5 cm2 in water, which would require a constant  current of 0.75 mA. The  Secondly it is best to limit the concentration of the colloid at any point, so it is  best to stir it as well. Which ppm concentration works best?   Opinions differ greatly. We think 10 ppm are sufficient. More than 15 ppm are  said to tend to clumping of colloids and silver ions.    How can I measure the ppm concentration?  Because colloids are electrically non-conductive, they can only be  measured  optically. If you use a ppm meter, you can determine only the 80-85% silver  ions, which are always produced simultaneously with colloids. The ppm of  all silver particles (ions and colloids) would therefore be calculated as [final  ppm reading - initial ppm reading] * 1.2. The ppm of the colloids alone would be  [final - initial] * 0.2. Can I determine the concentration by taste?  Sure! 10 ppm taste slightly bitter. We recommend that you go by the  taste, if  you don’t have a ppm meter (it should simply slightly metallic, noticeable, but  not too strong). Can I measure the particle size of colloids?    With a laser pointer, even light smoke  becomes visible. The Tyndall Effect is  caused by reflection of light by very  small particles in suspension in a  trasnparent medium. It will increase to  the third power of particle size  (measured in nm = nano meter) for  any given concentration, so a weaker  beam indicates smaller particles.  The  brightness of a laser beam in a solution of 1 ppm / 10 nm is 100 times higher,  compared to 10 ppm / 1 nm, although it has 10 times lower ppm!   It is generally accepted that only clear to light gold silver colloids have  particle sizes small enough to be effective. Ionic silver has an absorption band  in the uv, and thus is virtually clear. As more atoms aggregate into a particle,  the absorption band moves from the uv into the violet, blue, green, yellow,  orange and red. Since the color of a substance is the complement of the color  absorbed colloidal silver will go from clear to very light yellow, gold, orange,  red, blue and green. Colloids that contain a broad range of sizes can absorb  wavelengths across the spectrum resulting in brown and black.   Does it need a separate control electronics?    Not really. The purpose of additional electronics is primarily the increase of  voltage, and the miniSilver®  has it already integrated in the switching power  supply. Although the miniSilver does not provide a constant current control, this  is not necessary, because even with an exponential increase in conductivity,  you get sufficiently good results, if you stop the process in time (only slight  milky particle clouds visible).  Our philosophy  is to keep devices simple and yet  affordable.
