便携式气相色谱法快速测定空气中的环氧乙烷和环氧丙烷

摘要

建立一种利用便携式气相色谱仪快速测定空气中环氧乙烷和环氧丙烷的方法，两者能实现完全分离，检出限分别为0.6 mg/m3、0.7 mg/m3，方法的精密度与准确度较好，且检测结果与实验室常规固定式气相色谱法的检测结果差异无统计学意义（p>0.05）。该方法经实际应用，效果良好。%We developed the method for the determination of ethylene oxide and propylene oxide in the air by portable gas chromatography (portable GC). A good separation was achieved between ethylene oxide and propylene oxide. The determination limits of ethylene oxide and propylene oxide were 0.6 mg/m3, 0.7 mg/m3, respectively. The method had good accuracy and precision, and no significant differences with the test results were obtained between the portable GC and routine laboratory GC. The method was finally successfully applied to the working site.
