The introduction of chloroform into the nebulising gas of a LC/MS electrospray interface (ESI), in a perfectly controlled way, leads to the formation of intense adducts (M+Cl) when a mobile phase containing HMX (1,3,5,7-tetranitro-1,3,5,7-tetrazacyclooctane or octogen) and RDX (1,3,5-trintro-1,3,5-triazacyclohexane or hexogen) is eluted. This LC/MS method allows the direct analysis of aqueous samples containing HMX and RDX at the pictogram level without a concentration step. The method is used to determine HMX and RDX concentrations in ground water samples from a military site.
以完全可控的方式将氯仿引入液相色谱/质谱电喷雾接口（ESI）的雾化气体中，当洗脱含有HMX（1,3,5,7-四硝基-1,3,5,7-四氮杂环辛烷或奥克托今）和RDX（1,3,5-三硝基-1,3,5-三氮杂环己烷或黑索今）的流动相时，会导致形成强烈的加合物（M + Cl）。这种液相色谱/质谱方法允许直接分析含有皮克级HMX和RDX的水性样品，无需浓缩步骤。该方法用于测定军事基地地下水样品中的HMX和RDX浓度。
