In addition to the testing we perform on every batch made, we also send samples to an independant laboritory to ensure quality, safety & compliance with legislation. Due to our academic background & contacts, we also have a full test lab available to us at Bristol University research department which include an Electron Microscope & other useful test equipment. Rather handy!

Many thanks to Dr Chris Neal.

  
  TEM Analysis  
 

Transmission electron microscopy (TEM) is a microscopy technique whereby a beam of electrons is transmitted through an ultra thin specimen, interacting with the specimen as it passes through. An image is formed from the interaction of the electrons transmitted through the specimen; the image is magnified and focused onto an imaging device, such as a fluorescent screen, on a layer of photographic film, or to be detected by a sensor such as a CCD camera.

The photos show the particles & we esitmate the largest particle is around 40nm. True nano sized particles! Click the pic to enlarge.

 

  
  Independant Analysis  
 

We know we make very good solutions and have been for many years. Having the product tested independantly confirms the quality and safety of our solutions. They also include tests for bacteria such as Staph & E. Coli which is very important.

Also note the Silver content below & pH at 8.46, which is excellent. You really don't want the pH over 8.5 as it is too alkaline.

As part of the certification, the following notes apply:

1. Silver present whilst not required under the UK drinking water test schedule and was high at 14000 ugs/l

2. Turbidity test indicated an FTU (Formazin Turbidity Unit) result of 1.12 against a maximum level of 4.0 and was most likely due to the high levels of silver. In general drinking water at a municipal water supplier’s filtration farm would have an FTU turbidity of 0.5 at the point of delivery to the end user
