20世纪50年代起环氧乙烷开始用于医院灭菌,医疗机构引入环氧乙烷灭菌器始于上世纪90年代中期,主要用于怕热怕湿医疗器械的灭菌。随着环氧乙烷灭菌器在的不断普及,环氧乙烷灭菌监测中的问题也引起了广泛的关注。而环氧乙烷灭菌生物指示物的抗力水平在灭菌效果监测中尤为重要。
滕州市浩瀚色谱仪器技术服务有限公司，建立了医疗器械成品库空气中环氧乙烷浓度的顶空气相色谱测定方法。空气样品用纯水吸收，用PQS填充柱分离，氢火焰离子化检测器（FID）检测。在本法的测定条件下，环氧乙烷在0～15．768ug／mL浓度范围内线性良好，相关系数r=0．9992，相对标准偏差RSD〈2．1％，低检出限1ug／mL。本方法可满足医疗器械成品库空气中环氧乙烷浓度检测的要求。

In the 1950s, ethylene oxide began to be used for hospital sterilization. The introduction of ethylene oxide sterilizers in domestic medical institutions began in the mid-1990s and was mainly used for sterilization of medical devices that are afraid of heat and humidity. With the increasing popularity of ethylene oxide sterilizers in China, the problems in the monitoring of ethylene oxide sterilization have also attracted widespread attention. The level of resistance of ethylene oxide sterilized biological indicators is particularly important in the monitoring of sterilization effects.
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. established a method for determining the concentration of ethylene oxide in the air of medical equipment finished products by headspace gas chromatography. The air sample was absorbed in pure water, separated by a PQS packed column, and detected by a hydrogen flame ionization detector (FID). Under the conditions of this method, ethylene oxide has good linearity in the concentration range of 0 to 15.768 ug/mL, the correlation coefficient is r=0.9992, the relative standard deviation is RSD<2.1%, and the minimum detection limit is 1 ug/ mL. The method can meet the requirements for detecting the concentration of ethylene oxide in the air of the finished product library.
