General description: A graphitized carbon black (GCB) can be non-porous or porous. The graphitization process results in a highly pure surface with great adsorption and desorption (if required) properties. Surface interactions depend solely on dispersion (London) forces. These particles are:
• Granular
• Friable
• Used for molecules with an analyte size relative to C3-C20+ n-alkanes
• Hydrophobic (can be used in high humidity environments)

Generally, GCB adsorbents offer weaker relative adsorptive strength compared to carbon molecular sieve (CMS) adsorbents, and similar relative adsorptive strength compared to spherical graphitized polymer carbon (SGPC) adsorbents. Our Carbotrap products are a type of GCB adsorbent.
• Particles are 20/40 mesh
• These large particles allow high flow rates without excessive pressure drops

General description: Carbotrap® C was used for the sampling and quantitative analysis of microbially produced volatiles using thermal desorption-gas chromatography.
General description: Carbotrap®/Carbopack Adsorbent can withstand high bake-out temperature without losing the mechanical and chemical integrity. It has a high affinity for isoprene and does not retain significant amounts of water. Furthermore it has a tendency to pulverize if it is packed too tightly.
