Ethylene oxide gas chromatographThe basic principle is that the detection method for residual ethylene oxide in medical supplies is to use a headspace sampler for injection, followed by capillary column separation, and detect its content using a hydrogen flame detector. After heating and equilibrating the tested sample (gas-liquid and gas-solid), take a portion of its volatile gas and enter itgas chromatograph.
Ethylene oxide is a commonly used sterilizing agent for medical devices, which has the characteristics of strong penetration ability and good sterilization effect, and is widely used in the disinfection of medical supplies. However, ethylene oxide itself is a toxic gas. If the sterilized product cannot fully evaporate the ethylene oxide gas and the residual toxicity reaches a certain level, it will pose a threat to the human body.
The residual ethylene oxide in medical protective equipment has strong irritants to the human body and is a toxic and carcinogenic substance. Therefore, in the production process of masks, it needs to be analyzed for 7 days to release ethylene oxide. Only after the detection reaches the safety content standard can it be put on the market. At present, the most effective method for detecting residual organic solvents in medical device epoxyethane and packaging materials is headspace gas chromatography.
Refer to the national standard: GB/T 16886.7-2015 Biological Evaluation of Medical Devices Part 7: Residual Ethylene Oxide Sterilization. The GC-LT ethylene oxide gas chromatograph favored by Dalian Blue Sky can identify residual amounts of ethylene oxide and provide comprehensive, efficient, and accurate solutions.
