Determination of ethylene oxide residues in medical protective equipment by gas chromatography
Determination of ethylene oxide residues in medical protective equipment by gas chromatography Details:

Name: capillary column
Specifications: 30m*0.32mm*0.25um
Model: PEG-20M
Application: Determination of ethylene oxide residues in medical protective equipment by gas chromatography

Masks are personal guards against the new coronavirus. Ethylene oxide is used for sterilization and disinfection in the production process of disposable medical masks. Why does ethylene oxide have the effect of sterilization? Let us understand the composition, types, properties and sterilization principles of ethylene oxide together, and uncover the mystery of sterilization of disposable medical masks!

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a gas chromatography method to detect the residual amount of ethylene oxide in medical protective equipment such as masks and protective clothing, and provide data support for manufacturers to improve the sterilization process. Gas chromatography adopts headspace injection and FID detector. The mass concentration of ethylene oxide has a good linear relationship with the chromatographic peak area in the range of 0.5-8 μg/mL. The detection limit is 0.10 μg/g, and the quantification limit is 0.35. μg/g. The relative standard deviation of the determination results of ethylene oxide was 1.73% (n=6), and the average recovery was 94.3%-99.3%. The method is easy to operate, has high precision and accuracy, and is suitable for the determination of ethylene oxide in medical protective equipment.
