Lourdes Hydrofix Hydrogen Inhalation Testing 2020
We are going to perform a hydrogen gas flow measurement test of the Lourdes Hydrofix Premium Edition.
There are three methods for the hydrogen gas measurement test. Using a gas chromatography, gas sampling & mass flow controller.
The method using a mass flow controller is mainly used to detect the amount of hydrogen gas passing through a specific space such as industrial piping and it is not suitable. On the other hand, methods using a gas chromatography and a gas sampling are appropriate for measuring the hydrogen gas output in a specific spot.
In other words, you can measure the amount of hydrogen gas actually emitted from the tip of the cannula.
Gas chromatography requires large-scale equipment such as those found in university research institutes, and gas sampling is the most widely used reliable alternative.
For measuring the amount of hydrogen gas of a hydrogen gas inhaler.
The difference is whether you can measure numbers down to small units.
First, there are some points to note
When comparing hydrogen gas inhalers, there is a problem that the notation of hydrogen concentration is really difficult for ordinary people to understand.
This is because the testing methods and the definition of the descriptions for hydrogen products are not regulated and rely on the manufacturers. As a result, the information provided by the manufacturers are often manipulated, unclear and misleading.
Hydrogen gas is the smallest and lightest molecule in the universe and has an ability to escape quickly into the atmosphere. Therefore, the hydrogen concentration changes greatly depending on the location where the hydrogen gas concentration is measured.
You actually inhale hydrogen gas from (here) the nose piece, therefore, the measurements taking by (this area) the electrode plates and (this point) pitcher lid connecting part, etc
Do not indicate the actual amount of hydrogen gas output of the product. In fact, it is not at all useful information.
Also, the actual hydrogen gas output of the product cannot be measure correctly if the length of the cannula tubing, or connected to other devices and parts when taking a measurement.
Therefore, it is necessary to use the dedicated cannula provided for the product and measure the hydrogen flow at the tip of the cannula nosepiece when measuring the hydrogen gas concentration of the hydrogen gas inhaler. In addition, the hydrogen gas concentration depends not only on the size and quality of the electrode plate, but also on its structure and technology. So it cannot be simply calculated from the voltage and other factors. Some provide the estimated amount of hydrogen gas output by calculation as the hydrogen gas concentration.
However, that is only a fictitious numerical value at the electrode where the hydrogen is generated and the concentration is the highest.
Unfortunately, those fictitious values are far from the amount that can be actually inhaled. In addition to improper and unclear test methods and measurement locations, the most confusing and misleading information may be the percentage notation of hydrogen gas output.
The percentage is a ratio to something, so it can change completely depending on the situation.
Common misconception is that the percentage ratio to "what" is completely overlooked and the hydrogen gas concentration is determined based solely on the percentage "number."
The amount of hydrogen gas that can be actually inhaled in one minute needs to be converted to "milliliter", otherwise, it is meaningless.
In other words, it is not simply that 4% is high and 2% is low. Inhalation of the hydrogen gas used in medical clinical trials at Japanese university hospitals is typically 1.3% and 2%.
The percentage here is the ratio to the average human respiratory volume of about 10,000ml per minute, so when converted to actual volume, 1.3% is 130ml/min, and 2% is 200ml/min.
Another thing to keep in mind is that depending on the water use, the direct electrolysis produces ozone gas, chlorine gas, and hypochlorous acid in addition to hydrogen gas.
Products with low hydrogen purity without technology to separate and extract the only hydrogen, often mislead people by specifying the percentage of hydrogen purity as hydrogen concentration.
Actually, this is only the ratio of hydrogen gas in the large amount of all gases generated, and only a few percents of the air inhale is hydrogen gas, and it is only a trace of hydrogen gas when the actual amount of hydrogen gas is converted to milliliter per minute.
Since there are many inhalation devices in which oxygen and other gases are mixed in addition to hydrogen, the amount and strength of the gas bubbles generated cannot be the standards for comparing the amount of hydrogen either. In other words, the amount of hydrogen that can be actually inhaled per minute cannot be known unless the proper measurement is taken at the tip of the cannula. Today, we will perform a gas sampling method to measure the amount of hydrogen gas
Emitted per second from the tip of the cannula nosepiece. In order to obtain accurate measurements, we will be using an accessory cannula provided with the product and one of the two nosepiece holes is sealed with silicone. This is to prevent outside air from being sucked into the test tube during gas sampling.
A 100ml gas sample will be drawn into a test tube, and the hydrogen concentration can be determined from the change of color of the test tube caused by a chemical reaction with hydrogen gas. This time, drawn time will be set to 1 second in order to measure the amount of hydrogen gas output per second.
By comparing the color of the test tube with the colorimetric table, you can see that it contains 2% hydrogen gas.
1 draw = 100ml
Suctioning duration: 1 second
Hydrogen gas concentration: 2%
2ml/sec = 120ml/min
100ml of the sample was dawned in 1 second and resulted in a hydrogen concentration of 2%
2% is the ratio to 100m of air at the tip of the nosepiece.
The measurement results show that 100m of the sample contains
2% of hydrogen gas, so the amount of hydrogen gas contained in 100ml is 2ml per second
2ml per second, 120ml per minute.
In conclusion, it was proven that at least 120ml of hydrogen gas per minute was generated from the tip of the nosepiece.
