Abstract

An ultraviolet (UV) irradiation-gas-liquid chromatographic (GLC) detection procedure was used to confirm the presence of polybrominated biphenyl (PBB) residues in sample extracts after GLC quantitation. Chromatograms of PBB standard and sample extract solutions showed similar photodecomposition peak patterns dependent on time and intensity of UV irradiation. Confirmation of PBBs in sample extracts by this procedure was possible for any amount detectable by the GLC system employed. Prolonged UV irradiation resulted in complete disappearance of all PBB peaks from the chromatogram, permitting their distinction from background peaks due to extraneous sample material unaffected by UV irradiation.

摘要

采用紫外（UV）照射-气相色谱（GLC）检测程序，在GLC定量后确认样品提取物中多溴联苯（PBB）残留的存在。PBB标准品和样品提取物溶液的色谱图显示，取决于UV照射的时间和强度，它们具有相似的光分解峰型。通过该程序，可以对所采用的GLC系统可检测到的任何量的样品提取物中的PBB进行确认。长时间的UV照射导致色谱图中所有PBB峰完全消失，从而能够将它们与受UV照射影响的外来样品材料产生的背景峰区分开来。
