Product FAQ's


1.What is ppm?

It’s an acronym of “parts per million” representing how much part in a million.
Gas concentrations in a liquid are usually expressed in mass ratio and gas concentrations in a gas are expressed in volume ratio. Furthermore ppb (parts per billion) represents how much part in a billion.

10000ppm = 1%

1ppm = 0.0001%

1ppb = 0.0000001%

 


2. About the concentration of dissolved hydrogen.

The amount of saturated hydrogen in 1000 g of water is 0.00162 g.
0.00162(g)/1000(g)=0.00000162(=1.62ppm: mass ratio) at 20 ℃, 100 % hydrogen gas.

Calculating the volume of 0.00162 g of hydrogen gas is as follows;
Molecular weight of hydrogen gas H2 is 2
The volume of 1-mol gas is 24 L
0.00162(g)÷2(g)=0.00081(mol)
24(L)×0.00081(mol)=0.0194(L)
The amount of saturated hydrogen in 1L of water (=1000 g) is 0.0194 L


3. About the hydrogen concentration in breathing air.

The normal air we breathe in consists of 78 % nitrogen, 21 % oxygen, 0.04 % carbon dioxide and 0.00005 % hydrogen in volume.
The HIT system generates 30 mL hydrogen of 99 % or more purity in a minute, while an adult who is relaxed breathes in 6000 mL air in a minute.
Therefore you can inhale the air including about 0.5 % of hydrogen by using the HIT system: 30 mL/6000 mL×99=0.495 %


4. When and how long should I inhale hydrogen?

You can inhale hydrogen whenever and as long as you like. But some reports say that such intermittent inhalation as the alternation of 15/30-minute inhalation and 45-minute break is more effective than continuous inhalation. Also it’s said that changing the hydrogen concentration in our body would switch our body to a better condition regardless of what time.
Using the HIT system, you can inhale hydrogen with doing something else.


5. Are there any risks or difficulty breathing in hydrogen inhalation?

Hydrogen inhalation is adopted in medical treatment. The safety of hydrogen inhalation has already confirmed. One example is that hydrogen is added into divers’ gas cylinders to prevent them from submarine sickness or nitrogen narcosis.
An adult who is relaxed breathes in 6000 mL of air in a minute and the HIT system generates 30 mL of hydrogen in a minute. As you will inhale generated hydrogen with breathing normal air, you don’t need to worry about difficulty breathing.


6. Would hydrogen be a danger because of its flammability?

Hydrogen is stable gas and never flames by itself. Hydrogen mixed with oxygen may ignite but doesn’t ignite if its concentration is not more than 4.1% or not less than 74.2% The purity of hydrogen generated from HIT system is 99% or more, so you don’t need to worry about ignition.


7. I don’t have any sense of inhalation.

HIT system supplies high purity hydrogen without adding air flow.
Therefore the flow rate of hydrogen supplied from HIT is so small that you can feel just normal breathing, not any sense of inhalation. You can confirm the generation of hydrogen by seeing the bubbles in the level indicator.


8. How much purity and amount of hydrogen does HIT system generate?

The HIT system generates about 30 mL hydrogen of 99 % or more purity in a minute, which boasts the highest level among the portable hydrogen generators; that is as of November 2017.

9. How does the HIT system generate hydrogen?

It generates hydrogen gas and oxygen gas by electrolysis of water.
The generated hydrogen and oxygen are separated inside the main unit, and then hydrogen gas flows from the hydrogen outlet to the inhaler, while oxygen gas flows out from the pressure release outlet.


10. How long can I continuously use it?

A round of operation automatically stops after 30 minutes. You can press the start/stop button to restart it immediately.


11. How long can I use a bag of electrolyte?

You can operate about 30 rounds of 30-minute running with a bag of electrolyte. (It depends on the running circumstances)
Please change the electrolyte if the last change of electrolyte was two weeks before, no matter how many times you operated it. 


12. What are the components of the electrolyte?

It can’t be disclosed.


13. Can electrolyte be substituted with water?

Electrolyte can be substitute with distilled water only.


14. How long does HIT system run with a battery?

You can operate at least 2 rounds of 30-minute running with a full-charged battery.


15. How long is the life of a battery?

About 500 cycles.


16. How long is the warranty period? How long is its useful life?

The warranty is one year. Its useful life depends on the frequency of operations or the running circumstances. Under the proper conditions, the life of the device is about 3000 hours.


17. How often should I change the electrolyte/ distilled water?

You need to change the electrolyte/ distilled water in case of following:
* The LED indicator blinks RED (showing the amount of electrolyte/distilled water in not enough).
or
* The last change of electrolyte/ distilled water was two weeks before.


18. Is it easy to change the electrolyte/distilled water?

It’s very simple with only 2 steps.
– 1) Completely dispose the old electrolyte/ distilled water.
– 2) Pour the all electrolyte from a new bag/ pour 30 ml of distilled water to HIT system.


19. How can I clean the inside of the tank?

The inside of the tank can be cleaned by changing the electrolyte/distilled water. That’s enough to keep the tank clean and use only electrolyte or distilled water.


20. Are there any other tasks to maintain it?

No need to change parts or something. Your task is just regular change of electrolyte/distilled water.


21. Is it OK if I sterilize the nasal inhaler or the inhaler tubes by boiling?

They cannot be sterilized by boiling. If you want to sterilize them, please use alcohol. Because they are made of polyvinyl chloride (PVC), they aren’t heatproof.

22. Is it made in Japan?

Yes, it’s made in Japan.


23. Is there a patent for HIT system (La Briller Elan)?

The patent is now pending. (The patent application number is 2017-117503)


24. Does it happen to generate ozone? Are there any risks to inhale ozone?

As HIT system works with high electrolyzing efficiency, it doesn’t generate ozone.
