Applications of pyrolysis-gas chromatography and pyrolysis capillary gas chromatography in explosive and propellant analysis are reviewed, including the identification of explosives and propel- lants, the investigation of the thermal decomposition of nitrocellulose (NC), cyclotetramethylene tetranitramine (HMX)and cyclotrimethylene trinitramine (RDX), and the study of the wear- reducing mechanism of polyurethane additive in propellant gain.
A rewiew of the application of capillary electrophoresis (CE) to explosive analysis, including different mode of separation, various kinds of detectors, and the CE chips used in CE, was presented. Prospects of the application of CE, a new, effective and rapid technique of separation were discussed, and some new trends of development in this field were suggested.
The process involves no alkali metals, chlorides or transition metals such as chromates, and thus produces propellant and explosive grade ammonium perchlorate of high purity and with no associated instability or pollution problems.
Propellant and explosive manufacturers must treat day-to-day waste streams, and the government must treat overage and obsolete rocket motors.
