| 摘 要： | 本文研究了使用光离子化检测器便携式气相色谱仪，直接测定空气中ｍｇ／ｍ３级苯系物（苯、甲苯、乙苯、邻、间、对位的二甲苯及异丙苯）的快速分析方法。方法的线性范围为０～１００ｍｇ／ｍ３，相关系数均在０．９９９以上，方法的变异系数分别为２．９～１２．５％（５ｍｇ／ｍ３），３．４～７．９％（３０ｍｇ／ｍ３），方法最低检测限达０．２～１．０ｍｇ／ｍ３。

| Abstract: | The direct determination method of mg/m 3 level aromatic hydrocarbons(benzene,toluene,ethyl benzene,o xylene,m xylene,p xylene and i propyl benzene)has been studied with portable gas chromatograph with photoionization detector(PID).The method shows a good linearity between 0 100mg/m 3 of above benzenes,the correlation coefficients are all above 0 999,RSD s are 2 9 12 5%(5 mg/m 3),3 4 7 9%(30 mg/m 3),and the determination limits are 0 2 1 0mg/m 3. |
