Patel, Dhananjay I. published the artcileEvaluation of new, sputtered carbon solid-phase microextraction fibers with multi-functional group test mixture, Category: esters-buliding-blocks, the main research area is sputtered carbon solid phase microextraction fiber multifunctional test mixture.
We report the first fabrication of sputtered carbon, solid-phase microextraction (SPME) fibers. These fibers have competitive extraction capabilities compared with the com. carbon wide range (CWR) SPME fiber. This report also includes a demonstration of a newly developed SPME test mix that includes 15 different compounds with a wide range of functional groups and chem. properties. The fiber fabrication process involves sputtering carbon onto fused silica fibers, and the effects of throw distance on the morphol. of the carbon coatings were studied. Four different carbon coating thicknesses were evaluated, with PDMS added as a stationary phase. These fibers were characterized with multiple anal. techniques, including SEM (SEM), XPS, water contact angle (WCA) goniometry, as well as headspace (HS) and direct immersion (DI)-SPME-GC-MS. The best (11.5 μm) sputtered carbon SPME fibers, with and without PDMS, were evaluated using the new evaluation mix and compared with the com. CWR fiber and a previously sputtered/developed silicon fiber. The new probe mix helped elucidate differences among the fibers, which would have been missed by current com. test mixes. The sputtered carbon SPME fibers showed similar functional group selectivity as com. CWR fibers. However, the sputtered carbon fibers showed higher responses per volume compared with the com. CWR fiber, indicating the porous morphol. of the sputtered carbon has the ability to overcome large phase thickness/volume discrepancies and increase the relative recovery for various compounds
