The authors applied mass spectrometry to estimate nitrogen compounds in Kuwait petroleum distillates(290 to 310°C). Nitrogen compounds were condensed from gas oil by Florisil liquid chromatography. Carbon number distribution of each compound types was measured by low voltage ionization method. The abundance order of the type of nitrogen compounds were as follows: CnH2n-5N(0.024%)CnH2n-7N(0.0075%)CnH2n-17N(0.0032%)CnH2n-oN(0.0017%)CnH2n-15N(0.0097%)CnH2n-11N(0.0070%)CnH2n-13N(0.0024%)Distribution of carbon number was existed from C10 to C21, and apex of distribution was shown from C13 to C16.
