Analysis of Nitrogen Species in Gas Oils Using High Performance Liquid Chromatography and Fourier Transform Ion Cyclotron Resonance Mass Spectrometry
DownloadFall 2012
The nitrogen content of products derived from oil sands bitumen is important, as nitrogen causes problems in upgrading and hydrotreating. Normal phase high performance liquid chromatography (HPLC) has been previously used to attempt separation of the nitrogen group types (pyrrole and pyridine)...

Development and Characterization of New Stationary Phases for Hydrophilic Interaction Liquid Chromatography
DownloadSpring 2014
Ibrahim, Mohammed Elsayed Abdelatif
Hydrophilic interaction liquid chromatography (HILIC) has gained high popularity among separation scientists in the last two decades due to its ability to retain polar analytes. Many new HILIC stationary phases with different selectivities have appeared in the recent literature. Such developments...
