环氧乙烷(EO)是一种广谱低温灭菌剂，可在常温下杀灭各种微生物，包括芽孢、结核杆菌、细菌、病毒、真菌等。同时EO穿透性很强，可以穿透微孔达到产品内部相应的深度，从而大大提高灭菌效果，目前大多数无菌医疗器械生产企业普遍采用环氧乙烷灭菌。然而在杀灭微生物的同时，残留在医疗器械中的环氧乙烷会对使用者的身体产生一定程度的伤害。经动物实验表明，环氧乙烷不仅具有急性毒性，还具有致过敏性、

Determination of ethylene oxide residues in masks
Determination of ethylene oxide residues in masks Details:

Name: Capillary Column
Specification: 30m*0.25mm*0.25um
Model: PEG-20M
Application: Determination of ethylene oxide residues in masks

In 2020, with the outbreak of new coronavirus pneumonia, masks have become the first line of defense against the epidemic. While all mask manufacturers are working overtime to make masks, what needs to be done is not only to meet the requirements in terms of production quantity, but also to provide Quality assurance, so the determination of ethylene oxide residues in masks is particularly important.
Ethylene oxide (EO) is a broad-spectrum low-temperature sterilant that can kill various microorganisms at room temperature, including spores, tuberculosis, bacteria, viruses, and fungi. At the same time, EO is very penetrating and can penetrate the micropores to the corresponding depth inside the product, thereby greatly improving the sterilization effect. At present, most sterile medical device manufacturers generally use ethylene oxide sterilization. However, while killing microorganisms, the ethylene oxide remaining in the medical device will cause a certain degree of harm to the user's body. Animal experiments show that ethylene oxide is not only acutely toxic, but also allergenic,
Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. keeps pace with the times and has developed a PEG-20M capillary column for the determination of ethylene oxide residues in masks, with high column efficiency, good separation and satisfactory results.
