Abstract

The self-assembly of carbon nanotubes (CNT) on the inside wall of a steel capillary was presented to fabricate a microtrap for the adsorption/desorption of trace organics. The microtrap functioned as a nanoconcentrator and an injector for GC. The CNT were deposited as a thin film by catalytic chemical vapor deposition from either CO or C 2H 4 as the precursor. The CNT microtraps showed high capacity adsorption, fast quantitative desorption, and the process had excellent precision (RSD below 2%). CNT films could be deposited in a steel capillary for the use in different analytical applications. This is an abstract of a paper presented at the 229th ACS National Meeting (San Diego, CA 3/13-17/2005).
