医用口罩及医用防护服中环氧乙烷的测定
医用口罩及医用防护服中环氧乙烷的测定 详细信息：

Chromosorb 101  HP 60～80目；玻璃柱长2m*3 mm
适用于：安捷伦6890,7820,7890,8860,8890,4890,5890

在这次新冠肺炎疫情防控期间,为防疫物资及时供给,国务院应对新型冠状病毒感染的肺炎疫情联防联控机制医疗物资保障组印发了《关于疫情期间执行医用一次性防护服辐照灭菌应急规范(临时)的通知》(以下简称《应急规范》).目前,我国国标医用防护服大多采用环氧乙烷灭菌,需要7~14天时间,根据《应急规范》采用辐照灭菌技术,则将这个时间缩短到1天以内.

浩瀚色谱（山东）应用技术开发有限公司建立顶空-气相色谱法测定医用口罩和医用防护服中环氧乙烷残留量的分析方法。通过实验优化了测定方法和条件,确定了色谱柱类型、顶空平衡时间和平衡温度,并进行了加标回收实验。在相应的浓度范围内线性关系良好,r=0.9996,环氧乙烷低检出限为0.02μg/mL,当称样量为1.0g,定容体积为5mL时,检出限为0.1μg/g。方法可以满足标准要求,对口罩和防护服中环氧乙烷残留量检测具有重要意义。

Determination of ethylene oxide in medical masks and medical protective clothing
Determination of ethylene oxide in medical masks and medical protective clothing Details:

Chromosorb 101 HP 60～80 mesh; glass column length 2m*3 mm
Applies to: Agilent 6890, 7820, 7890, 8860, 8890, 4890, 5890

During this new crown pneumonia epidemic prevention and control period, in order to ensure the timely supply of epidemic prevention materials, the State Council's Joint Prevention and Control Mechanism for the New Coronary Virus Infection Pneumonia Epidemic Prevention and Control Mechanism Medical Materials Security Group issued the "Irradiation Sterilization of Medical Disposable Protective Clothing During the Epidemic Period". Emergency Specifications (Temporary) Notice" (hereinafter referred to as "Emergency Specifications"). At present, most of my country's national standard medical protective clothing is sterilized by ethylene oxide, which takes 7 to 14 days. According to the "Emergency Specifications", irradiation sterilization is used. Technology reduces this time to less than 1 day.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established an analytical method for the determination of ethylene oxide residues in medical masks and medical protective clothing by headspace-gas chromatography. The determination method and conditions were optimized through experiments, the column type, headspace equilibrium time and equilibrium temperature were determined, and standard addition and recovery experiments were carried out. The linear relationship is good in the corresponding concentration range, r=0.9996, the minimum detection limit of ethylene oxide is 0.02μg/mL, when the weighing sample is 1.0g and the constant volume is 5mL, the detection limit is 0.1μg/mL g. The method can meet the standard requirements and is of great significance for the detection of ethylene oxide residues in masks and protective clothing.
