A quantitative liquid chromatography/electrospray ionization tandem mass spectrometry (LC/ESI‐MS/MS) method was developed for the analysis of the explosive, octahydro‐1,3,5,7‐tetranitro‐1,3,5,7‐tetrazocine (HMX). In negative ionization mode, HMX forms an acetate adduct ion [M + CH 3 COO] − , m/z 355, in the presence of a small amount of acetic acid in the mobile phase. The ESI collision‐induced dissociation (CID) spectrum of m/z 355 was acquired and the transitions m/z 355 → 147 and m/z 355 → 174 were chosen for the determination of HMX in samples. Using this quantification technique, the method detection limit was 1.57 µg/L and good linearity was achieved in the range 5–500 µg/L. This method will help to unambiguously analyze environmentally relevant concentrations of HMX. Copyright © 2006 John Wiley & Sons, Ltd.
