The Origins of Polyatomic Ions in ICP-MS
NSF, Analytical and Surface Chemistry Program
$168k direct costs, $245k total for 2003-2006
Collaborative project with M. Gordon
My group identifies polyatomic ions and measures their abundances; Gordon’s group
calculates the structures of the ions. Combining this information allows measurement of
the temperature corresponding to the region the ions are formed.
