A method has been developed to determine the concentration of nitroaromatics and nitramines in drinking water at levels below those previously achieved by gas chromatography. The nitroaromatics and nitramines are extracted from water using toluene and isoamyl acetate, respectively. The extracts are analyzed via a gas chromatograph equipped with a DB-1301 widebore fused-silica capillary column and an electron capture detector. Method detection limits of 0.003 micrograms/L for 2,6-dinitrotoluene (2,6-DNT), 0.04 micrograms/L for 2,4-dinitrotoluene (2,4-DNT), 0.06 micrograms/L for 2,4,6-trinitrotoluene (TNT), 0.3 micrograms/L for cyclotrimethylenetrinitramine (RDX), and 6.0 micrograms/L for cyclotetramethylenetetranitramine (HMX) have been obtained using this method.
已开发出一种方法，用于测定饮用水中硝基芳烃和硝胺的浓度，其检测水平低于之前气相色谱法所能达到的水平。分别使用甲苯和乙酸异戊酯从水中萃取硝基芳烃和硝胺。萃取物通过配备DB - 1301宽口径熔融石英毛细管柱和电子捕获检测器的气相色谱仪进行分析。使用该方法获得的方法检测限为：2,6 - 二硝基甲苯（2,6 - DNT）为0.003微克/升，2,4 - 二硝基甲苯（2,4 - DNT）为0.04微克/升，2,4,6 - 三硝基甲苯（TNT）为0.06微克/升，环三亚甲基三硝胺（RDX）为0.3微克/升，环四亚甲基四硝胺（HMX）为6.0微克/升。
