Measuring PPM ( Parts per Million )
Colloidal Silver Concentration

This section provides information documenting the various methods used to attempt to measure the concentration ( PPM ) of "home-brewed" colloidal silver. However, it should be noted that there is no way to properly and accurately measure or classify colloidal silver without professional testing. There is even a great discrepancy between results obtained from different labs who have tested the same products.

Cellulitis Treated with Colloidal Silver

"This can be a life threatening infection in my case so I waste no time in treating it. I take a 12oz cup every hour and a half to two hours until the infection is gone. Anything less does not seem to be effective. It usually takes about 3 days to cure, which is a vast improvement over a 10 day hospital stay on IV antibiotics followed followed by 12 weeks of oral antibiotics..."

Methods Commonly Used to Determine Concentration/Strength of Home Colloidal Silver

Laser Light Pen

Utilizing a laser light after colloidal silver production is a favorite method utilized by "home-brewers". While using a laser light to detect a tyndall effect in no way indicates the total concentration of colloidal silver, it does have several uses.

1. The presence of a tyndall effect indicates minute particles in suspension. When creating colloidal silver via the electrolysis method in distilled water, the tyndall effect demonstrates that the production of colloidal silver has been successful. Since most colloidal silver produced via LVDC ( Low Voltage Direct Current ) is between 80 - 85% ionic, the presence of a tyndal effect indicates the presence of both silver particles and ionic silver.

2. The tyndall effect via a laser light pen can provide those experienced with a method of quality control. Through trial and error, a user gains a feel for how strong a product is and should be, and the silver solution may be meticulously studied for tiny silver flakes and other particulate contaminants. Laser lights and video camera may be utilized to study how silver particles are dispersed into the water during production.

Pure Water Testing Meter ( Hanna PWT Meter )

Utilizing a Hanna PWT Meter to estimate the PPM of colloidal silver is one of the most valueable methods available without access to a laboratory.

Before making colloidal silver, the quality of the distilled water is measured. The best distilled water for making colloidal silver will read below 1.0 on the Hanna PWT Meter. The purest water we've tested ( via our own distillation ) read 0.2uS.

Since the PWT meter actually measures conductivity, near-accurate results depend upon the purity of the water, silver, and cleanliness of all equipment used during colloidal silver production.

Once the distilled water is checked for quality, it is a good idea to add the distilled water to the production vessel ( the colloidal silver generator ), wait about 2 minutes, and then re-check for contamination.

Make a note of the final reading. After production, let the colloidal silver sit for awhile, between 15 mins and an hour. Test the final product.

The equation for estimating the PPM of the colloidal silver is as follows:

( Final Meter Reading - Initial Distilled Water Reading ) X Adjustment/Conversion Factor = PPM Colloidal Silver.

A standard conversion factor used by many producers is 1.2; however, this number will not be entirely accurate, and depends upon many variables that cannot be easily isolated. The 1.2 specification applies to Silvergen Colloidal Silver Generators specifically, and was developed by comparing a laboratory analysis ( total silver content measured in PPM ) with readings from the Hanna PWT meter. Silvergen colloidal silver is 80-85% ionic, 15%-20% particulate. Keep in mind that the Hanna PWT meter will not register any particulate silver in the CS product; this is why a conversion factor is required.

Even if one has not had batches tested to properly classify and measure colloidal silver concentration, the Hanna PWT meter is still an excellent tool to assist the homebrewer with quality control. By making notes and developing a baseline, one can at least be certain that an end batch is within acceptable parameters.

I purchased a Colloidal silver maker last year, the sollution is 3 to 5 parts per million and particle size is between .45 and 1.2 microns. What is this good for please? Its quite hard to find a some kind of table on the web giving the different solutions ans their usages. Thanks. lela – Oregon January 31, 2010 - 01:56 Subject: making colloidal silver I have tried to make colloidal silver at home and am confused as to how much distilled water to use and how long to leave the rods in the water. Do I or don't I add a couple drops of salt water? If I don't, nothing ever happens, yet I read that it is actually silver chloride if I use salt. I would really like some info on this. I have read many articles but none of them give me any specifics on how long to leave the rods in or what amount of water to use. And how strong is it if you do it in say a quart of water for 30 minutes? Can anyone help me? Louis Anderson – New Port Richey Fl April 26, 2009 - 20:14 Subject: conduction in distilled water I have a device that was intended to dispense copper and silver in a swimming pool. When used with two silver dollars it makes a high production silver generator. My question is I was taught that distilled water is an insulator and the tests I've made seem to confirm that. I had to add salt to generate a current flow. How do you generate a current flow thru the insulating distilled water? Reply to Louis Anderson Silver Serf July 05, 2009 - 02:08 Subject: Re: conduction in distilled water Louis, Pure distilled water has a very low conductivity, (in this sense an insulator) however as electrolysis progresses, silver ion and particles are released into the solution. Assuming your water and silver are both pure, any increase in conductivity of the solution can be regarded as concentration of siver colloid (ppm). Adding salt as a conductive agent will in fact speed electrolysis but will also rapidly increase the current which will knock off chunks of silver instead of ions and micron range colloids, and also create silver chloride (a grey film) which will ultimately give you a bad case of the blues! (Argyria) Use only pure silver and pure distilled water, it may take longer but will produce a superior quality CS. Oscar – Florida April 13, 2009 - 15:22 Subject: meter request Hi, We are looking for an instrument which can measure the silver concentration in hypo (used fixer) before it will be discharged. The standard that we have to meet is the 0.6 mg/l, so we want to know, which meter do you suggest to us to buy? We appreciate your prompt reply. amira February 18, 2009 - 18:50 Subject: colloidal silver generator I would like to purchase the generator but need more info please. Help! Amira Reply to amira FRED BYNUM – Detroit Mi 48239 November 29, 2009 - 09:52 Subject: Re: colloidal silver generator Why buy a generator when you can make 1 yourself. 4 small aligator clips. / 3 - 9volt battries. speaker wire 16 or 18 gauge. about 12'' long. interconnect the 3 battries togeather. put the aligator clips on the 4 ends of the wire. i use 2 bars of pure silver.99.999 pure. only use distilled water/ no tap water/no reverse osmose/ no absopure / no bottle water / no spring water. get your self a red lase light pen. there is a test you need to do on your colloidal silver when it's done. Get yourself a ppm tester onlne they run about $20 to $25.00 . Clean clean everthing before hand.and KEEP IT THAT way all through the prosecces. you will need some steel wool fine no course. this is to clean your sillver in between heating your distilled water. you start out with DISTILLED water at room Tempture. you will need to containers of the same size that will fit into your microwave. wash your contianers out and dry them. wash your silver and use the the steel wool rinse. pour you distilled water into ( 1 ) container not to full. get a piece of stryfoam just about an inch or 2 larger than your container. poke a smallhole the size of a pencil. now about a 1/2'' apart poke a second hole about the same size. NOW this is important. push ( 1 ) of your aligator clips through the hole and put your silver bar on the clip. Now do the same to the other clip make sure the bars DO NOT TOUCH each other. if they do they will short out your batt. DO NOT ADD ANYTHING TO THE DISSTILLED WATER / NO SALT OR ANYTHING. NOW PLACE YOUR CONTAINER OF DISTILLED WATER INTO YOUR MICROWAVE OVEN. you want to heat your water until it just starts to boil that will take about 5 minutes. get yourself 2 pot holders so you dont' get burned. take it out and put your stryfoam bars into the water. ( REMEMBER DON'T LET THE ALIGATOR INTO THE WATER ONLY THE SILVER BARS ) OTHER WISE YOU WILL CONTAIMNATE YOUR COLLOIDAL SILVER. DONT LET THE SILVER TOUCH EACH OTHER AS WELL YOU WILL NEED TO HEAT THE WATER SEVERAL TIMES. WATCH IT CLOSELY NOW. THE WATER WILL TURN A PALE YELLOW. NOW YOU DONE. YOU HAVE JUST MADE YOUR FIRST BATCH OF IONIC COLLOIDAL SILVER. TAKE YOUR LASER PEN AND SHIE IN INTO YOUR FRESHLEY MADE COLLOIDAL SILVER YOU NOW CAN SEE THE NANO PARTICALS OF SILVER. COLLOIDAL MEANS SUPPENDED STORE YOUR COLLOIDAL SILVER IN A GLASS CONTAINER. LET IT COOL DOWN FIRST OH THAT SECOND CONTAINER IS NOW NEEDED YOU WILL NEED A COUPLE OF COFFE FILTERS TO STRAIN IT FIRST. GET A RUBBER BAND WRAP IT AROUND YOUR FILTER AND CONTAINER SO YOU DON'R SPILL IT. IF YOU LET COOK LONGER IT'S NOT ANY BETTER THE PARTICALS GET TO LARGE AND FALLOUT OF SUPbleepedON. THATS NOT GOOD YOUR PPM TESTER IS NOW NEEDED ANYTHING BELOW 10 PPM IS OK anything lower than 5 ppm is in effecttive. The taste of colloidal silver is metal testing like when they first came out with aluminum cans. you can taste it. ioinc means it is 100 times better. WHEN MY DAGUTHER WAS SICK WITH THE FLU I PUT IT INTO FROZEN ORANGE JUICE I MADE A GALLON AT A TIME WITH 12 OZ OF IONIC COLLOIDAL SILVER IT WORKED LIKE A CHARM 4 DAYS LATER SHE WENT BACK TO WORK. 11-11-09 I USE IT TO KEEP MY SINSUS CLEAR. EYE INFECTIONS, I SPRAY INTO MY MOUTH FOR COPD LUNG INFECTIONS. I hope this helps you.
