Objective To develope the residue determination methods of ethylene oxide for medical supplies.Methods Samples were soaked in hot bath with 60 ℃ and lasting 40 min,then used the head-space gas chromatography(HS-GC) and quantitatived the residue determination of ethylene oxide by extemal standard method.Results The linear of ethylene oxide in the range of 0.1 ～ 10.0 mg/L was good,and its recovery was within 82％～ 93％.The relative standard deviations (RSD) of ethylene oxide was less than 5％,and its limits of detection (LOD) and limits of quantification (LOQ) respectively were 1 mg/L( S/N ≥3 ) and 5.0 mg/L ( S/N ≥10).Conclusions The method of head-space gas chromatography(HS-GC) can quickly and easily determine the ethylene oxide residue of medical supplies,and it can satisfy the needs of the laws and regulations of domestic and foreign and disinfection monitoring of medical supplies.
