> Hydrogen concentration 1,0 ppm measured with H2 blue Kit titration drops
Comment from Karl Heinz Asenbaum:
Apart from the name, the Lourdes hydrogen generator has nothing to do with the source in the Catholic pilgrimage site, because it has nothing to do with hydrogen. Even if one believes the most optimistic statement about the “holy” water in the pilgrimage site of Lourdes, although it is not scientifically proven, this water contains 0,08 mg/l of dissolved hydrogen gas at the source (not in the shipping canister!). So you would have to drink 6,25 liters of it to reach a therapeutic minimum. The naming “Lourdes” is just a publicity stunt and is based on a well-cultivated myth.
The device requires a minimum filling quantity of around 1 liter.
This makes it ideal for multi-person households because hardly anyone drinks a liter at a time alone.
The hydrogen bubbles created within it are powerful. They are prevented from gassing out of the water by a floating plastic disc. However, unlike hydrogen boosters, no hydrogen pressure is built up.
As always, I measure with an enrichment time of 15 minutes because within this period the hydrogen dissolves well even in harder water.
Let's see the result measured with H2 Blue Kit® titration drops in time lapse. The eleventh drop no longer decolorizes, so we achieved a hydrogen concentration of 1,0 ppm.
Since we have one liter of water here, this corresponds to a dose of 1 mg. This is definitely well above the recommended threshold of 0,5 milligrams and is therefore acceptable.
The hydrogen is produced in water ionizers, hydrogen boosters or hydrogen infusion machines (HIMs) by using direct current to electrolyze (divide) water molecules (H2O). At the end of the electrolysis process, the divided water molecules produce the two gases hydrogen (H2) and oxygen (O2), separated by a membrane, in a ratio of 1:2. There are different processes for this:
Water ionizer: Both electrodes in the water at a distance from the membrane. The membrane has large pores. The hydrogen water above becomes basic and below it becomes acidic.
Lourdes: Both electrodes in the water directly on the membrane (“zero distance electrolysis” or SPE = Solid Polymer Electrolyte) The membrane has small pores and only lets protons through (PEM = Proton Exchange Membrane) The H2 water above remains the same in pH, below it becomes sour. If possible, the sensitive membrane at the bottom of the pot should not be touched or cleaned mechanically. An emptied pot should always stand on the damp anode sponge to prevent the membrane from drying out.
Booster/HIM: Both electrodes directly on the PEM membrane, but only the top one in the water. Hydrogen water above remains the same in pH. Oxygen escapes into the air.
How is hydrogen water made?
When it was discovered that only dissolved hydrogen was crucial for the specific antioxidant effect of water, an industry developed that pressed H2 gas at high pressure into multi-layered bags of water. Unfortunately, this is expensive and causes major transport and waste problems.
Hydrogen water can also be produced chemically, for example by allowing metallic magnesium to react together with an acid in the water to release hydrogen gas. On the one hand, such hydrogen fizzy tablets release alkaline ions into the water, but on the other hand, the pH value must be kept well below pH 7 by the acid components in order for hydrogen to be produced. These tablets are not available in many countries due to approval problems, but in individual cases they can reach values of over 3 mg/liter. Depending on the dosage, magnesium can also cause side effects that are not known from other types of hydrogen water.
Until recently, hydrogen-rich water was primarily produced using stationary electrolytic water ionizers. Depending on the design, these hydrogen values reach from 0,5 to 2,8 mg/L in the flow process and at the same time increase the pH value. The “Lourdes” hydrogen generator, on the other hand, does not change the pH value due to its PEM membrane, but cannot dissolve more than 1,2 mg/L hydrogen gas in the water. However, it is cheaper to purchase than a strong water ionizer, but it also does not have a built-in water filter and should therefore only be used with water that has already been filtered. Even reverse osmosis water with low conductivity can be used.
Hydrogen is very reluctant to dissolve in water except under high pressure. This is exactly what hydrogen boosters do. This type of device also works with a PEM cell, but due to a pressure-tight seal, the hydrogen is not so easily degassed from the water and forces it to dissolve in it more than with an open device like the Lourdes. Such devices are currently only available as small, battery-operated devices for on the go, while the “Lourdes” result: hydrogen-rich water without changing the pH value.
Lourdes Hydrogen Water Generator | Produce hydrogen-rich water yourself
In the electrolysis part at the bottom of the glass pot, hydrogen gas is released into the pot, which should dissolve in the water as extensively as possible (maximum 1,6 mg/l). But this takes a lot of time because the hydrogen bubbles you see push up very quickly and are reluctant to dissolve in the water.
The trick of the “Lourdes” system consists of the float disk on the sliding rod, which catches the hydrogen bubbles below the water surface before they outgas. This gives them longer time to dissolve into the water. The disc must always be well below the water surface.
Briefly press the start button 1 x (10 minutes production time), 2 x (20 minutes) or 3 x (30 minutes). The longer the production time is chosen and the smaller the amount of water in the pot, the higher the hydrogen concentration will be.
The hydrogen water is now ready and should either be consumed immediately or immediately filled to the brim in a glass or stainless steel bottle with a tight seal so that the dissolved hydrogen cannot outgas. Preserved for more than 12 hours with a tight seal.
