Cover Story: New sputtered carbon SPME fibers showed similar functional group selectivity as commercial CWR fibers, where the sputtered morphology has again shown the ability to overcome phase thickness/volume discrepancies and increase the relative recovery for some compounds. Additionally, a new SPME evaluation mix was developed, which consists of 15 compounds with different functional groups and chemical properties. Pentane, chloroform, 2-picoline, and sulfolane provided valuable insights into coating/stationary phase behavior, which would otherwise have been missed by the traditional probe mixes. N,N-dimethylamine and dicyclohexylamine, which are present in the Kovats’ and Grob’s test mixes, continue to show their value in the current study. The sputtered carbon fibers showed better responses per volume of the coatings than commercial CWR fibers. View this paper.
