新型冠狀病毒肺炎爆發(fā)后,口罩作為重要的防護(hù)手段,需求量激增,很多口罩生產(chǎn)企業(yè)24h連軸生產(chǎn),仍然不能滿足疫情期間口罩需求,一些生產(chǎn)紙巾,紙尿褲等企業(yè)也相繼加入了口罩生產(chǎn)大軍.環(huán)氧乙烷(EO)是廣譜,的氣體殺菌消毒劑,廣泛應(yīng)用于各類醫(yī)療器械的消毒中,但環(huán)氧乙烷是一種中樞神經(jīng)抑制劑,刺激劑,有致突變性,嬰兒毒性和致畸特性,為一類致癌物,長(zhǎng)期接觸有致癌的風(fēng)險(xiǎn).此外,國(guó)家標(biāo)準(zhǔn)GB 19083-2010《醫(yī)用防護(hù)口罩技術(shù)要求》也明確規(guī)定經(jīng)環(huán)氧乙烷滅菌的口罩,其環(huán)氧乙烷殘留量應(yīng)不超過10μg·g-1.因此,口罩中環(huán)氧乙烷的測(cè)定顯得很有必要.

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(cè)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(shí)驗(yàn)優(yōu)化了測(cè)定方法和條件,確定了色譜柱類型,頂空平衡時(shí)間和平衡溫度,并進(jìn)行了加標(biāo)回收實(shí)驗(yàn).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(shí),檢出限為0.1μg/g.方法可以滿足標(biāo)準(zhǔn)要求,對(duì)口罩和防護(hù)服中環(huán)氧乙烷殘留量檢測(cè)具有重要意義.

Chromosorb 101 HP 60～80 mesh; glass column length 2m*3 mm
For Shimadzu GC-2010

After the outbreak of the new coronavirus pneumonia, the demand for masks as an important means of protection has surged. Many mask manufacturers continue to produce 24 hours a day, but they still cannot meet the demand for masks during the epidemic. Some companies that produce paper towels and diapers have also joined the mask production army. Ethylene oxide (EO) is a broad-spectrum, highly efficient gas sterilization disinfectant, widely used in the disinfection of various medical devices, but ethylene oxide is a central nervous system depressant, stimulant, mutagenic, and infantile. Toxicity and teratogenic properties, it is a class of carcinogens, and long-term exposure has the risk of cancer. In addition, the national standard GB 19083-2010 "Technical Requirements for Medical Protective Masks" also clearly stipulates that masks sterilized by ethylene oxide, their epoxy The residual amount of ethane should not exceed 10 μg g-1. Therefore, the determination of ethylene oxide in masks is necessary.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. 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, and the type of chromatographic column was determined. The headspace equilibration time and equilibration temperature were measured, and the standard addition recovery experiment was carried out. The linear relationship was good in the corresponding concentration range, r=0.9996, the minimum detection limit of ethylene oxide was 0.02μg/mL, and when the weighing sample amount was 1.0 g, when the constant volume was 5 mL, the detection limit was 0.1 μg/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.
