[0002] In pharmaceutical companies, the use of ethylene oxide for sterilization is a commonly used sterilization method. However, after the sterilization is completed, there will be a certain amount of sterilization waste gas in the sterilizer. Since the sterilization waste gas in the sterilizer is toxic, it cannot be directly discharged into the atmosphere. Therefore, the sterilization waste gas must be purified before it can be discharged. When purifying the sterilization waste gas, the waste gas discharged from the ethylene oxide sterilizer is usually treated with a gas analyzer.

[0003] After searching, a Chinese patent with the announcement number CN214969533U discloses an ethylene oxide analyzer, which is provided with an air inlet connected to a heating fan on the bottom plate of the analysis chamber and an exhaust port on the top plate, so that when the door panel is closed, the control device starts the heating fan to blow hot air continuously into the analysis chamber through the air inlet, and the hot air passes through the analysis chamber from top to bottom and is discharged from the exhaust port, and the circulation is repeated. The flowing air continuously analyzes ethylene oxide, and the hot air accelerates the entire analysis process. In addition, the temperature sensor and the pressure sensor provided in the analysis chamber monitor the temperature parameters and pressure parameters in the analysis chamber in real time and feed back to the display screen through the control device, so that the operator can observe the situation in the analysis chamber in real time; however, when the above-mentioned analyzer purifies the exhaust gas discharged from the ethylene oxide sterilizer, it is often unable to purify the gas in a targeted manner according to the type of gas, and it is necessary to match the analyzer that meets the type of gas according to the type of gas.
