| Abstract |
A small CNT sponge preconcentrator for the GC analysis, designed to determine complex mixtures of volatile organic compounds (VOCs), is described. CNT sponges were synthesized by CVD process using ferrocene and 1,2-dichlorobenzene as the catalyst precursor and carbon source, respectively. The sponge morphology and CNT
structure was characterized by SEM, TEM, EDS, XPS, and Raman. CNT sponges cut into a rectangular block (3x2x45mm2, 5mg) was inserted between metal frits in a 1/4"" Quartz tube. After sample trap by the adsorbent, the flow direction through the preconcentrator is reversed, and the thermally desorbed analyte is directly introduced into the GC capillary column module. Preconcentration factor of greater than 100 is observed for VOCs compounds.
