Gas chromatographic analysis of trinitrotoluene from the continuous process

Determination of nitroaromatics in biosludges with a gas chromatograph/thermal energy analyzer

“…Of special interest was the question whether this emission contains specific polycyclic aromatic compounds. It is wellknown that brown coal contains picene derivatives, originating from triterpenoids with a-and /3-amyrin structures (1)(2)(3)(4)(5). Thus, it may be expected that these compounds pass over to the flue gas at the beginning of the combustion process.…”

Recent advances in ambient mass spectrometry of trace explosives

“…Analysis of trace explosive by GC/MS goes back to the 1970s, 72, 73 and has most commonly focused on the detection of nitro compounds and organic nitrates. The power of chromatographic separation, combined with mass spectral identification, has led to broad ranging applications from identification of synthesis or manufacturing impurities, 49, 74 to detection in complex matrices such as soil, 14 wastewater, 75 sea-water, 76 and plant material.…”

Analytical Chemistry of 2,4,6-Trinitrotoluene

“…A GC procedure using a flame ionization detector was developed to control product quality and study variables in the continuous TNT process (ref 69).…”
