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：

口罩是抗擊新型冠狀病毒的貼身小衛士,一次性醫用口罩生產過程中使用環氧乙烷滅菌消毒。

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:

Masks are personal guards against the new coronavirus. Ethylene oxide is used for sterilization and disinfection in the production process of disposable medical masks.

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.
