吸附管采样-毛细管柱气相色谱法测定环境空气和工业废气中的丙酮

Determination of acetone in ambient air and exhaust air by tube adsorption and capillary gas chromatography

文章建立了以活性炭为填料的吸附管采集环境空气或工业废气中的丙酮,CS_2进行解吸,并用毛细管柱气相色谱进行定性定量的方法。结果表明该方法简单灵敏,线性范围良好,检出限低,精密度好,定性定量准确;经实际样品测定,完全能满足环境空气和工业废气中丙酮的监测要求。

The method of determination of acetone in ambient air and exhaust air was established in the pa-per, which was using activated charcoal tube adsorption/carbon disulfide desorption and determined by capillary gas chromatography. The method was simple and sensitive, it also had broad linear scale, low MDL, good precision,accuracy qualitative and quantitative accuracy. The method can satisfy the demand of monitoring of acetone in am-bient air and exhaust air via the sample test.
