全球新冠肺炎的暴发使得防护产品的需求量剧增。介绍了防护产品的灭菌方法,并详细阐述了环氧乙烷的灭菌范围及其优缺点、防护用品中环氧乙烷残留量的考核值、环氧乙烷检测、灭菌程序等。希望研究结果为生产企业使用环氧乙烷灭菌防护用品提供理论指导。 


对口罩中环氧乙烷残留量进行监测是确保口罩质量安全的重要手段。浩瀚色谱（山东）应用技术开发有限公司）建立了口罩中环氧乙烷含量定量检测的气相色谱法。具有操作简单、检出限低等优点。对8种不同材质和放置时间的实际口罩样品进行检测。发现市售外科口罩样品中环氧乙烷的残留量为1.52μg·g^-1,符合国标要求。使用后的口罩样品中环氧乙烷的残留量随着时间延长残留量下降。建立的方法可用于口罩中环氧乙烷残留量的快速筛查和确证分析。

  The global outbreak of new coronary pneumonia has caused a sharp increase in the demand for protective products. The sterilization method of protective products is introduced, and the sterilization range of ethylene oxide, its advantages and disadvantages, the assessment value of ethylene oxide residue in protective equipment, the detection of ethylene oxide, and the sterilization procedures are described in detail. It is hoped that the research results will provide theoretical guidance for manufacturers to use ethylene oxide sterilization protective equipment. 


Monitoring the residual amount of ethylene oxide in masks is an important means to ensure the quality and safety of masks. Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a gas chromatography method for quantitative detection of ethylene oxide content in masks. It has the advantages of simple operation and low detection limit. 8 kinds of actual mask samples of different materials and storage time were tested. It was found that the residual amount of ethylene oxide in the commercially available medical surgical mask samples was 1.52 μg·g-1, which met the requirements of the national standard. The residual amount of ethylene oxide in the mask samples after use decreased with time. The established method can be used for rapid screening and confirmatory analysis of ethylene oxide residues in masks.
