This paper is a survey of ion chromatography (IC) methods used at Sandia National Laboratories to characterize energetic materials. Information is given for the analysis of a variety of materials including pyrotechnic, explosive, and propellant materials that contain perchlorate, smoke compositions, a primer mixture, and explosive materials such as pentaerythritoltetranitrate (PETN), An appendix contains details for those who may wish to apply the analyses in their laboratories.
