摘　　要：设计并建立了气相色谱/石英炉(Ⅲ型)原子吸收联用系统,在选定条件下对系统的主要性能作了研究与测试。以四乙基铅为样品,线性范围0～8 ng,检测极限3.8×10^(-12)g/sec,最小检测量为30pg。作合成样品分析,相对标准偏差为3.31～4.12％,回收率为94.6～104％。This paper presents a combined system of gas chromatograph and silica-furnace(Ⅲ) atomic absorption spectrophotometer Its main performances are studied and tested with tetraethyl lead solution under selected conditions. The linearity is maintained over the range of 0-8ng. The detection limit is 3.8×10^(-12)g/sec. The RSD for analyzing synthetic samples is 3.31-4.12% and the recovery is 94.6-104%.
