High Speed Liquid Chromatographic Separations of Thermally Labile High Energy Compounds. Part II. Infrared Spectral Characterization of Micropreparative HPLC Fractions,

摘要

Techniques were developed for infrared spectral characterization of samples separated by high performance liquid chromatography. Samples in the range of 30-40micrograms were chromatographed with essentially analytical resolution using a Corasil II column. Fractions trapped from the chromatograph were concentrated onto approximately six milligrams of potassium bromide and examined in the infrared as micropellets using a beam condenser. Consistently good spectra could be obtained using these techniques when injecting samples in the range of 30-40micrograms into the chromatograph. Separation and spectral characterization of nitroglycerinethyl centralite, a composite modified double base propellant extract, paranitrololunene, dinitrotoluene and trinitrotoluene, (TNT),TNT-tetryl and HMX -RDX are discussed.
