溶剂解析气相色谱法对室内空气中苯和苯系物的测定研究

目的：探讨气相色谱法对室内空气中苯和苯系物进行测定。方法：使用活性炭管采集，CS2解析，PEG－红色担体不锈钢填充柱分离，检测苯和苯系物的线性因子和计算因子。结果：线性回归情况良好，能比较好的定量；以某室内新装修家庭作为研究对象，发现不同样本浓度均小于0．09mg／m3，苯系物浓度综合低于0．9mg／m3。结论：溶剂解析气相色谱法所获得的结果准确可靠，且方式简单、线性范围广、重复性佳、检测速度快，能在实际分析过程中得到令人满意的结果。

Benzene and benzene series in the room air was estimated by solvent relief absorption gas chromatography

Objective:Using solvent relief absorption gas Chromatography to estimate the concentration of the Benzene and benzene series in theroom air.Methods:It adopted the active carbon tube to collect samples,which were relieved by CS2 absorption with PEG-stainless stee packed column. Results:linear regression turned all right,it can be accurate fixed the amounts.From the newly decorated apartment proceeds measurement,resultsshowed that in the above places the benzene concentration measured were all less than 0.0 9mg/m3 .Conclusion:Gas chromatography is accuracy,simple and good repeatability.The results obtained using this program seems to be satisfactory.
