During small-scale and medium-scale experiments, ozone generators are often selected to use oxygen as a gas source for experiments because the concentration of ozone is high.
Some engineering projects also choose oxygen as a source. Oxygen source refers to the raw material provided by the ozone generator for the ozone generator, which comes from oxygen generating machines or oxygen cylinders, with a purity of more than 90%.
So, what is the concentration of oxygen-oxidizing ozone generators generally?
Oxygen-oxidizing ozone generators are ozone generators that recombine the input oxygen after ionization to form ozone. The higher the concentration of oxygen in the air, the higher the concentration of ozone will be. Air source uses air as raw material, and the concentration of ozone generators is generally within 10 mg/L. This is because the ozone generator ionizes 21% of the oxygen in the air, while using oxygen as raw material ionizes more than 90% of the oxygen, so the concentration will be much higher.
The difference in oxygen content between air source and oxygen source is less than 4 times, but why is the concentration difference 10 times larger? There are other factors that affect the concentration of ozone, such as moisture content in the air, impurities, and pressure.
Therefore, if the concentration of ozone decreases, you need to find out whether it is due to a malfunction in the ozone generator or a problem with the feed gas.
