20世紀(jì)50年代起環(huán)氧乙烷開始用于醫(yī)院滅菌,醫(yī)療機(jī)構(gòu)引入環(huán)氧乙烷滅菌器始于上世紀(jì)90年代中期,主要用于怕熱怕濕醫(yī)療器械的滅菌。隨著環(huán)氧乙烷滅菌器在的不斷普及,環(huán)氧乙烷滅菌監(jiān)測(cè)中的問(wèn)題也引起了廣泛的關(guān)注。而環(huán)氧乙烷滅菌生物指示物的抗力水平在滅菌效果監(jiān)測(cè)中尤為重要。
滕州市浩瀚色譜儀器技術(shù)服務(wù)有限公司，建立了醫(yī)療器械成品庫(kù)空氣中環(huán)氧乙烷濃度的頂空氣相色譜測(cè)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(cè)器（FID）檢測(cè)。在本法的測(cè)定條件下，環(huán)氧乙烷在0～15．768ug／mL濃度范圍內(nèi)線性良好，相關(guān)系數(shù)r=0．9992，相對(duì)標(biāo)準(zhǔn)偏差RSD〈2．1％，低檢出限1ug／mL。本方法可滿足醫(yī)療器械成品庫(kù)空氣中環(huán)氧乙烷濃度檢測(cè)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.
