Description:Literature Seminar Abstract\n\nPetroleum production is a multib
 illion dollar global industry producing over nine million barrels of oil a
  day.  All unrefined petroleum contains sulfur which when combusted forms
  acid rain and smog producing SOx.  Complete sulfur removal during refini
 ng is challenging due to refractory molecular structures and difficulties 
 in their characterization.  Characterization would allow development of m
 ore efficient removal methods\, producing cleaner finished fuel.  Electro
 spray ionization coupled with high resolution mass spectrometry can provid
 e mass data for hydrocarbons in crude oil but poorly ionizes most sulfur c
 ompounds.  Improved ionization of sulfur containing compounds using dopan
 ts will be discussed and silver as a dopant for sulfur will be evaluated i
 n several crude oils through mass spectrometry data.  The use of dopants 
 provides an alternative method for characterizing refractory compounds in 
 crude oil samples.\n\n  4:00 pm
