依据HJ605标准所界定的方法采集GCMS数据,用AMDIS对污水底泥样品数据中的挥发性有机物进行鉴别。为对项目污水底泥样品特征的数据进行综合考量和深度挖掘,基于AMDIS原有格式的结果数据建立了Excel VBA程序模块,用于将污水底泥样品中挥发性有机污染物的定性识别及响应强度等数据导入至Excel的电子表。为更为准确高效的鉴别复杂污水底泥样品中的挥发性有机物,基于开发的Excel VBA程序模块,实现了从AMDIS的FIN数据文件直接生成库的VBA程序,从而使目标化合物库(*.MSL)按污水底泥挥发性测试实验系统进行了特征化。从而,这过程使目标化合物库不仅含有整个项目污水底泥的挥发性分析物,而且还含有系统特定的保留时间和保留指数等信息。基于此库,再用于AMDIS的保留时间或保留指数分析类型,可实现对整个项目的污水底泥样品进行更为准确、可靠的快速鉴别。
GCMS data were collected according to the method defined in HJ605 standard, and volatile organic compounds in wastewater sediment sample data were identified by AMDIS. In order to comprehensively consider and deeply mine the data of the project sewage sediment samples, an Excel VBA program module was built based on the result data of the original AMDIS format, which is used to qualitatively identify and respond to the volatile organic compounds in the sewage sediment samples Strength and other data into the Excel spreadsheet. In order to identify volatile organic compounds in complex sewage sediment samples more accurately and efficiently, based on the developed Excel VBA program module, a VBA program that directly generates a library from the AMDIS FIN data file is implemented, so that the target compound library (* .MSL ) Was characterized by the sewage sediment volatility test experimental system. Thus, this process allows the target compound library to contain not only volatile analytes throughout the project’s sewage sludge, but also system-specific retention times and retention indices. Based on this library, reused for AMDIS retention times or retention index analysis types, a more accurate, reliable and rapid identification of the entire project’s wastewater sediment samples can be achieved.
