Crude Oil's Polar Portion Yields To MS

Department: Science & Technology

A new method makes it easier to analyze asphaltenes, mostly aromatic compounds that make up the heaviest and most polar fraction of crude oil. As oil prices rise, asphaltenes are becoming increasingly important because of their high concentration in heavy oils and tar sands. Laser desorption ionization mass spectrometry usually works well for polar molecules, but the method has given widely varying molecular weight distributions for asphaltenes. Now, Andrew E. Pomerantz of Schlumberger-Doll Research . . .
