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)...

Preparation and Characterization of Stationary Phases for Hydrophilic Interaction Liquid Chromatography and Reversed Phase Liquid Chromatography
DownloadSpring 2016
High performance liquid chromatography (HPLC) has become an invaluable tool in modern chemical analysis. While reversed phase liquid chromatography (RPLC) is the most commonly utilized mode of HPLC, hydrophilic interaction liquid chromatography (HILIC) is gaining popularity due to its ability to...
