摘要
建立了热脱附-毛细管气相色谱法测定有机废气中丙酮和乙酸乙酯的检测方法。目标组分在曲线范围内线性良好,相关系数大于0.995,检出限低于0.078 mg/m3(采样体积以1.0 L计)。用该方法检测了企业产生的有机废气及厂界空气,实验结果表明该方法操作简单、灵敏度高、结果准确可靠,能够满足对实际样品的分析要求。
A method has been developed for determination of acetone and ethyl acetate using thermal desorption-gas chromatography. The related coefficient of standard curves is above 0. 995,and the detection limit is lower than 0. 078 mg / m3 when sampling volume reaches 1. 0 L. The results show that this method which detects the organic waste gas and the air of the factory produced by the enterprise,is easy to operate with high sensitivity,so as to be accurate and reliable,and can meet the requirements of the actual sample analysis.
