Evaluation of a new graphitized carbon black employed in sampling volatile organic compounds

Sampling and analysis of volatile organic compounds in air using a dualsorbent trap

“…The higher the specific surface area, the greater the retention capacity of the adsorbent due to increased van der Waals interaction forces. The retention offered by Carbograph 5, however, is superior to that expected on the basis of its specific surface area, probably due to the presence on its surface of geometrical active sites where a molecule can interact with more than one graphitic plane [11,14,15].…”

Evaluation of a new dualsorbent trap for organic pollutants of different volatility

“…In this trap, the"strong adsorbent" is a new high specificsurface (560 m 2. g-l) graphitized carbon black [ 17].…”

“…A new graphitized carbon black, Carbograph 5, which has a specific-surface area of 560 m 2 . g-1 and satisfactory BTVs and desorption recoveries for even the lighter polar compounds, has been studied recently [ 17]. An obvious solution for sampling mixtures of VOCs is to use complementary materials in order to increase the affinity for low-boiling compounds, while achieving quantitative desorption of the high-boiling compounds under suitable temperature and flow conditions [18][19][20][21][22][23].…”

Multi-layer Cartridges Filled with Multi-Walled Carbon Nanotubes for the Determination of Volatile Organic Compounds in Indoor Air

“…[4][5][6][7] Furthermore, other factors, including lifespan, mechanical intensity and convenience should also be taken into account. Because each adsorbent has a different retention property for VOCs, a kind of adsorbent can not be suitable for collecting all of the compounds with different volatility and polarity.…”
