1 Scope

GB/T 18340 provisions of this part of the mass spectrometry method of petroleum heavy fractions aromatic group composition quantitative calculation and qualitative analysis Volume requirements. This section applies to heavy petroleum fractions (boiling range 205 ℃ ~ 540 ℃) aromatic hydrocarbon fraction 18 aromatics and three kinds of aromatic thiophene Quantitative analysis of thiophene group composition. Samples should be free of olefins, the total sulfur content should be less than 1% of the total weight of the non-aromatic compound content of less than 5%. Principle 2 Crude oil is separated by column chromatography, an aromatic hydrocarbon fraction obtained by direct injection into the mass spectrometer system by electron bombardment to give the aromatic Mixed hydrocarbon fraction mass chromatogram. The mass spectral data of the class Ⅰ ~ Ⅶ aromatic characteristic peak intensity group and add each characteristic mass peak group package Including multi-isotopic molecular ion peak series and single isotope molecular ion minus 1 series, calculated according to the export of pure aromatic compounds inverse matrix 7 × 7 7 out of the relative content of aromatic hydrocarbons. According to the baseline and each aromatic family law is divided into nominal type (Type 0), overlapping the first type (type 1) and a second weight Stack type (type 2). Finally, calculate the class type 3 7 Total 21 kinds of aromatic hydrocarbons (Table 1) relative content.
