GASTIGER NO NO2 measuring device that measures NO2 emitted when plasma is generated in the atmosphere

Hello, this is RS Korea. I visited two places to confirm and demonstrate the NO NO2 produced when plasma is generated in the atmosphere. First, I would give a demonstration to the Korea XXXX Research Institute in Changwon, and then move to Gunsan to the Korea XXXX Research Institute to do the same demonstration. First, I visited the Korea XXXX Research Institute in Changwon,

We captured the moment while measuring NO and NO2 generated when general atmosphere is converted into plasma with high voltage. This is the important part. Number 1: Due to the nature of the electrochemical formula, there is a sensor that requires a certain amount of oxygen for each gas. Because the injected oxygen is continuously converted into plasma, there may be a lack of oxygen at the end of the experiment. In this case, the sensor may not operate properly. No. 2: In general, NO NO2 measurement is aimed at combustion gas analysis, not for the plasma market. In a combustion environment, the NO:NO2 generation ratio is generally 95:5, resulting in significantly lower NO2 than NO. This means that there is not much reason to make sensors with high NO2 concentration in the market. Therefore, the maximum range of our NO2 sensor was limited to 1000ppm. Solution 1 and 2 To prevent the oxygen deficiency phenomenon in solution 1 and the overrange phenomenon in solution 2, you can create an environment where you can create a mixed gas by injecting a certain amount of oxygen. Next, we moved to Korea XXXX Research Institute located in Gunsan.

This is a plasma-related device that I saw in the lab I arrived at. After opening this equipment and seeing the plasma reaction color, we will measure it with our device.

It is a similar reaction to the demonstration measured earlier. As a result, 1. In the plasma reaction, NO: NO2 is produced in a ratio of about 3: 1, but it may vary depending on the set voltage value and temperature value and various variables. 2. Because both oxygen and nitrogen flowing in are sprayed at high voltage, the oxygen in the reaction tank drops rapidly.3. A fairly high concentration of NO NO2 is generated.4. Therefore, it is necessary to set up a configuration that dilutes through the inflow of outside air. 5. It was a demonstration site where we could see that it was complete. thank you
