ABSTRACT:
The qualitative and quantitative analysis of nitrogen-containing compounds is accomplished by contacting in the presence of an acid a sample containing such a compound with an aromatic hydrocarbon, thereby converting the compound to a stable nitrogen-containing aromatic hydrocarbon. The sample now containing the nitrated aromatic hydrocarbon is then introduced in a carrier gas stream into a chromatographic column. The effluent stream from the column is passed through a gas chromatography detector, and the detector signal response obtained is compared with that produced by known amounts of a reference calibration sample.
