Onesummary:Ethylene oxide (EO) is used for disinfection of medical equipment, but it is a known carcinogen. Relevant regulations require regular testing during production and use. The solution for detecting ethylene oxide (EO) is to quantitatively determine the EO content in disinfected medical equipment using headspace gas chromatography. The gas chromatography scheme for residual ethylene oxide analysis in medical equipment has a reasonable instrument configuration, simple operation, and reliable results. It is a practical detection scheme for medical equipment manufacturers and hospitals.
