| 摘 要： | 气相色谱法具有较高的灵敏度和良好的线性关系。按照EPA QA／QC的要求，将该方法运用于实际样品分析。结果表明。水中汽油检出限为0．04mg／L。水中苯系物检出限为0．003-0．005mg／L,土壤中汽油检出限为0．5mg／kg，土壤中苯系物检出限为0.005-0．008mg／kg。样品加标回收率为97．1％～106．8％。变异系数为2．1％～4．6％，结果令人满意。

| Abstract: | Enrichment with purge\|trap, gas chromatography with the separation of DB\|624 capillary column and analyses on gasoline range organics & BTEX were discussed. The method had higher sensitivity and linearity. The results showed that detection limit of GROs was 0.04 mg/L in water & 0.5 mg/kg in soil, and that detection limit of BTEX was 0.003~0.005 mg/L in water & 0.005~0.008 mg/kg in soil. The recovery of gasoline range organics & BTEX was 93.7%~105.0%. The relative std. deviation was 2.1%~4.6%. The analysis result was satisfactory. |
