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.
