<p>PURPOSE: A sample concentrator is provided to ensure low operation temperature and efficient concentration of harmful sample gases by employing an adsorbent made of carbon nano tube-metal nano composite with high heat transfer efficiency. CONSTITUTION: A sample concentrator comprises a sample concentration part(110) which contains an absorbent made of a carbon nano tube-metal nano composite material filled in a first tube to adsorb sample gases, fixing members which are located on both ends of the carbon nano tube-metal nano composite material to fix the carbon nano tube-metal nano composite material, and a heating member which heats the first tube to remove the volatile organic compounds adsorbed in the carbon nano tube-metal nano composite material.</p> |
