Abstract
Carbon nanotubes (CNT) have some highly desirable sorbent characteristics which make them attractive for a variety of analytical applications. High adsorption capacity and rapid desorbability make CNT excellent candidates for micro-scale devices for gas and liquid-phase analysis. In gas-phase analysis one can implement a micro-concentrator or a micro-sorbent trap, which have been used in a variety of on-line chromatography and sensing applications. Interesting liquid-phase microtrapping applications include micro-scale solid-phase extraction (μ-SPE) and solid-phase micro extraction (SPME). In addition, the ease of surface functionalization, self assembly by chemical vapor deposition, and the formation of diverse polymer composites may well make CNT the high-performance sorbent of the future.
