Direct analysis of RDX and TNT in water by high-performance liquid chromatography
D.F. Goerlitz
1979, Open-File Report 79-916
A method for the determination of RDX (1,3,5-trinitro-1,3,5-triazacyclohexane) and TNT (2,4,6-trinitrotoluene) directly in water is given. The high-performance liquid chromatographic technique permits detection down to 0.1 microgram per liter in filtered water. No ancillary extraction or concentrating procedures are used....
