A quadrupole ion trap was used to characterize metallic, ceramic and p
olymeric materials by using laser ablation directly inside the storage
volume as a sampling and ionization method. A differentially pumped s
ample probe was utilized to facilitate sample changes and ion trap ele
ctrodes with extended hyperbolic surfaces were used to provide more un
iform ion storage fields. The effects of sample surface preparation an
d laser fluence were investigated for stainless-steel samples.
