H2 Blue detects dissolved H2 (molecular hydrogen) in water. It uses Methylene blue (biological tissue dye used as an indicator in medicine). H2 Blue reacts with hydrogen-rich water turning clear when the h2 concentration is at least 0.1mg/l (ppm).

Dissolved hydrogen levels are calculated by performing a titration where the H2 Blue reagent is added to a precise amount of water (6ml) which contains an unknown level of H2. The "blue" H2 Blue molecules react and turn "clear" in the presence of dissolved hydrogen gas (H2). As additional drops are added, the dissolved H2 molecules continue to be "consumed" until they are totally depleted.

This is called the "titration endpoint". When the endpoint has been reached, additional drops will no longer turn clear, and the solution will remain blue. By counting the number of drops of H2Blue required to reach the titration endpoint, and then multiplying the number of drops by 0.1(or dividing by 10), the level of dissolved H2 gas in mg/L (ppm, parts per million) can be determined. Example, 8 drops x 0.1 = 0.8 mg/L of dissolved H2

How H2 Blue works

Methylene blue is an oxidising agent which, in the presence of a platinum catalyst, reacts with dissolved molecular hydrogen to produce the reduced (clear) form of methylene blue: leucomethylene blue. 

The equation above shows that methylene blue is a blue colour in its oxidised form and then becomes clear when reduced during the reaction with H2. Below you can see how the structure of the methylene blue molecule changes after its reaction with H2.

Whilst using H2 Blue test a small quantity of water (6ml) and do not ingest the tested water. H2 Blue is not safe for human consumption and must be kept off of skin or anything that you do not wish to turn blue (it is a strong dye.)

The H2 Blue formula used is eco-safe and we can provide a data sheet upon request. The quantity recommended is 6ml so that you can accurately calculate hydrogen concentration. Store in a cool dry place.

If H2 blue freezes during shipping, allow thawing for a minimum of eight hours before use. Do not attempt to speed up the thawing process using a microwave or hot water.

How to use H2 Blue

To use H2 Blue first cover a surface with paper towels or something similar so that no surfaces are damaged/dyed. You have to work quickly with your hydrogen enriched water as the longer you wait the more H2 will escape. We also recommend using gloves, protective or old clothing and possibly eye protection. 

First measure 6ml of the hydrogen-rich water into the supplied beaker (which doubles up as storage for your H2 Blue bottle) ensuring the bottom of the meniscus is touching the 6ml line as shown below

Then add a drop of H2 Blue to it. The drop should turn clear. Continue to add drops, stirring after every one, until the water no longer turns clear. Count the amount of drops it takes for the liquid to stop turning clear. As mentioned previously, by counting the number of drops of H2Blue required to reach the titration endpoint , and then multiplying the number of drops by 0.1(or dividing by 10), the level of dissolved H2 gas in mg/L (ppm, parts per million) can be determined. For example, 8 drops x 0.1 = 0.8 mg/L of dissolved H2 .
