醫用口罩及醫用防護服中環氧乙烷的測定
醫用口罩及醫用防護服中環氧乙烷的測定 詳細信息：

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

在這次新冠肺炎疫情防控期間,為防疫物資及時供給,國務院應對新型冠狀病毒感染的肺炎疫情聯防聯控機制醫療物資保障組印發了《關于疫情期間執行醫用一次性防護服輻照滅菌應急規范(臨時)的通知》(以下簡稱《應急規范》).目前,我國國標醫用防護服大多采用環氧乙烷滅菌,需要7~14天時間,根據《應急規范》采用輻照滅菌技術,則將這個時間縮短到1天以內.

浩瀚色譜（山東）應用技術開發有限公司建立頂空-氣相色譜法測定醫用口罩和醫用防護服中環氧乙烷殘留量的分析方法。通過實驗優化了測定方法和條件,確定了色譜柱類型、頂空平衡時間和平衡溫度,并進行了加標回收實驗。在相應的濃度范圍內線性關系良好,r=0.9996,環氧乙烷低檢出限為0.02μg/mL,當稱樣量為1.0g,定容體積為5mL時,檢出限為0.1μg/g。方法可以滿足標準要求,對口罩和防護服中環氧乙烷殘留量檢測具有重要意義。

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.
