摘要
利用HP-PONA毛细管柱,热解析-气相色谱法测定作业场所中空气中的溶剂汽油。方法检测下限为2.6×10-4μg/ml,相关系数大于0.999,检出限为2×10-3μg,回收率达90%以上,相对标准偏差(RSD)小于3.0%。该方法操作简便,适用于工作场所空气中溶剂汽油的测定。
Using the HP PONA capillary colunm, thermal desorption gas chromatography-determination of the solvent in air in workplaces. Method detection limit is 2. 6 10-4g/ml, the correlation coefficient is greater than 0. 999, the detection limit is 2 10-3g, the recovery rate of above 90%, relative standard deviation (RSD) is less than 3.0%. The method is simple, suitable for the determination of solvent naphtha in workplace air.
