Establishment of a method for the determination of ethylene oxide and dioxane in polyethylene glycol 1 using vast chromatography. Method: HH-1 capillary column (30 m x 0.53 mm x 3.00) was used μ m) Program heating, hydrogen flame ionization detector. Results: Ethylene oxide and dioxane were found to be between 0.61 and 30.32, respectively μ G · mL-1, 5.85~292.6 μ The linear relationship between the peak area and the concentration range of g · mL-1 is good. The average recovery rate of ethylene oxide at high, medium, and low concentration levels is 106.9%, with an RSD of 3.5% (n=9); The average recovery rate of high, medium, and low concentrations of dioxane is 107.2%, with an RSD of 2.2% (n=9). Conclusion: The established determination method is sensitive and accurate, and can be used for the determination of ethylene oxide and dioxane in polyethylene glycol
