| Abstract |
Previously, we synthesized carbon nanotube (CNT) sponge which has porous, uniform, soft, flexible and freestanding structure. In this study, we made small-sized preconcentrator for gas chromatographic (GC) analysis using CNT sponges. Trace amount of volatile organic compounds existing in the air sample is adsorbed preferably onto the surface of CNT sponge. The enriched adsorbents are thermally (100–300 ℃) desorbed promptly from the CNT surface by appling electric DC power. GC analysis confirms that 100 times improvement of detection limit can be achieved using the preconcentrator. Therefore, the preconcentrator made of CNT sponge is advantageous in that it is driven with a small power consumption, has a small size, enables instantaneous desorption of the enriched sample, and has excellent desorption efficiency. |
