20世紀50年代起環氧乙烷開始用于醫院滅菌,醫療機構引入環氧乙烷滅菌器始于上世紀90年代中期,主要用于怕熱怕濕醫療器械的滅菌。隨著環氧乙烷滅菌器在的不斷普及,環氧乙烷滅菌監測中的問題也引起了廣泛的關注。而環氧乙烷滅菌生物指示物的抗力水平在滅菌效果監測中尤為重要。
滕州市浩瀚色譜儀器技術服務有限公司，建立了醫療器械成品庫空氣中環氧乙烷濃度的頂空氣相色譜測定方法。空氣樣品用純水吸收，用PQS填充柱分離，氫火焰離子化檢測器（FID）檢測。在本法的測定條件下，環氧乙烷在0～15．768ug／mL濃度范圍內線性良好，相關系數r=0．9992，相對標準偏差RSD〈2．1％，低檢出限1ug／mL。本方法可滿足醫療器械成品庫空氣中環氧乙烷濃度檢測的要求。

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.
