A method for the HPLC analysis of RDX and HMX on a novel copoly(vinylthiazole‐vinylimidazole) stationary phase [P(Th‐Im) phase] is described. Special elution order of RDX and HMX on this phase using methanol/water (60/40∼90/10) as mobile phase is HMX > RDX, which is quite different from those on a commercial RP‐18 phase. The chromatographic selectivities (α‐values) between RDX and HMX are 2.40∼2.55. This advantage can be used to identify the limited impurity of ca. 1 ppm RDX in HMX during the manufacture of HMX.
