摘要
采用顶空／气相色谱法（HS／GC）对土壤中挥发性芳烃顶空前处理条件、气相色谱分离、定性和定量分析条件进行了研究，优化了土壤中挥发性芳烃分析的顶空前处理条件和气相色谱分离条件，分析了方法的检出限、精密度及回收率等质量控制参数。在最佳条件下，方法检出限大多数小于2．0μ/kg（以2g样品计），精密度小于15％，回收率为90％-110％之间。
Volatile aromatic hydrocarbons in soils by HS/GC is studied. The conditions which include preparation of samples, GC system, quantative analisis, qualitative： analisis and HS system is talked about in this paper. The quality control procedures including MDL, precision and recovery are studied. In the best conditions, MDL is below 2.0 μg/kg（ by 2 g samples）, precision is less than 15% and standard recovery is between 90% and 110%.
