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.
