环氧乙烷(ethylene oxide,EO)在常温常压下为无色气体,4℃时冷凝为液体,沸点为10.4℃,具有高度的化学活性,易燃易爆.环氧乙烷具有广谱杀菌作用,属有效的化学冷灭菌剂之一.环氧乙烷常被用于工业灭菌与消毒,近年来在医院怕热怕湿医疗器械灭菌中也得到广泛应用.但环氧乙烷属于有毒气体,对许多物品具有很好的吸附性,灭菌物品必须等待残留气体完全挥发才可给病人使用.因此,了解残留毒性情况和准确测定灭菌物品中环氧乙烷残留量,对于其灭菌后物品安全使用非常重要.现就环氧乙烷在灭菌物品中残留量测定、毒性及职业危害的研究进展。

Porapak QS packed column for determination of ethylene oxide EO Details:

Stationary phase: polymer pellet

Particle size: 80-120 mesh

Specifications: 0.8m*1/8, 1.5m*1/8, 2m*3mm

Model: PQS/Porapak QS

Application: GB-T16886.7-2015 Biological evaluation of Medical Devices Part 7: Ethylene Oxide Sterilization Residues

Ethylene oxide (EO) is a colorless gas at normal temperature and pressure. It condenses into a liquid at 4 ° C and has a boiling point of 10.4 ° C. It has high chemical activity and is flammable and explosive. Ethylene oxide has a broad spectrum. Highly effective bactericidal action, it is one of the most effective chemical cold sterilizing agents. Ethylene oxide is often used in industrial sterilization and disinfection. In recent years, it has also been widely used in hospitals for the sterilization of heat and dampness medical devices. Oxygenethane is a toxic gas and has good adsorption to many articles. Sterilized articles must wait for the residual gas to completely evaporate before they can be used by patients. Therefore, understanding the residual toxicity and accurately determining the residual ethylene oxide in the sterilized articles. The amount is very important for the safe use of the articles after sterilization. Now, the research progress of the determination of the residual amount of ethylene oxide in the sterilized articles, toxicity and occupational hazards.
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. used PQS packed column to determine the residual ethylene oxide in medical equipment, and the external standard method was used for quantification.
