在這次新冠肺炎疫情防控期間,為防疫物資及時供給,國務(wù)院應(yīng)對新型冠狀病毒感染的肺炎疫情聯(lián)防聯(lián)控機制醫(yī)療物資保障組印發(fā)了《關(guān)于疫情期間執(zhí)行醫(yī)用一次性防護(hù)服輻照滅菌應(yīng)急規(guī)范(臨時)的通知》(以下簡稱《應(yīng)急規(guī)范》).目前,我國國標(biāo)醫(yī)用防護(hù)服大多采用環(huán)氧乙烷滅菌,需要7~14天時間,根據(jù)《應(yīng)急規(guī)范》采用輻照滅菌技術(shù),則將這個時間縮短到1天以內(nèi).

浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司建立頂空-氣相色譜法測定醫(yī)用口罩和醫(yī)用防護(hù)服中環(huán)氧乙烷殘留量的分析方法。通過實驗優(yōu)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(jìn)行了加標(biāo)回收實驗。在相應(yīng)的濃度范圍內(nèi)線性關(guān)系良好,r=0.9996,環(huán)氧乙烷低檢出限為0.02μg/mL,當(dāng)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(biāo)準(zhǔn)要求,對口罩和防護(hù)服中環(huán)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.
