Separation and characterization of polycyclic aromatic hydrocarbons and azaarenes using normal phase liquid chromatography and electrospray ionization mass spectrometry
DownloadFall 2016
Normal phase liquid chromatography (NPLC) is widely used for separating petroleum into compound classes, such as polycyclic aromatic hydrocarbons (PAHs) and polar nitrogen containing compounds. The charge-transfer and hypercrosslinked polystyrene NPLC phases provide unique selectivities for PAHs....

Studies of Fundamental Theories and Retention Mechanism of Charge Transfer and Hypercrosslinked Phases in Normal Phase High Performance Liquid Chromatography
DownloadSpring 2017
Polar compounds in petroleum, especially compounds containing nitrogen, cause numerous problems in the processing of oil, including deactivation of catalysts, corrosion, and storage instability. Chromatographic separation helps to identify and characterize these polar compounds at different...
