Ethylene oxide (EO) is an organic compound with the chemical formula C2H4O. It is a known carcinogen and is often used as a sterilizer. Relevant regulations require regular testing in production and use. Ethylene oxide residue According to GB/T 16886.7-2015 biological Evaluation of Medical Devices part 7: Ethylene oxide residue sterilization GB/T 14233.1-2008 Medical infusion, blood transfusion, injection equipment test method Part 1: Chemical Analysis Methods, GB19083-2010 Technical Requirements for Medical Protective Masks, ISO10993-7; 2008 “ethylene oxide (EO) and 2-chloroethanol (ECH) residue detection” in the gas chromatography for detection.
Our company’s ethylene oxide (EO) detection solution is to quantitatively determine the content of EO in the sterilized medical equipment with headspace air chromatograph. The instrument configuration of this solution is reasonable. Simple operation is a practical testing scheme for medical equipment manufacturers.
