从炭黑中提取的高分子量（> 300 道尔顿）多环芳香族化合物通过使用梯度洗脱的反相高效液相色谱进行分离。收集级分并通过质谱法和荧光分光光度法进行分析。虽然只有 15 种化合物能够得到肯定的鉴定，但其他 38 种化合物得到了初步的结构归属，其中包括几个大的硫杂环。
High-molecular-weight (> 300 daltons) polycyclic aromatic compounds which were extracted from a carbon black were separated by reversed-phase high-performance liquid chromatography using gradient elution. Fractions were collected and analyzed by mass spectrometry and spectrofluorimetry. While only 15 compounds could be positively identified, 38 others were given tentative structural assignments, among which were several large sulfur heterocycles.
