Descripción general

Carbotrap® C was used for the sampling and quantitative analysis of microbially produced volatiles using thermal desorption-gas chromatography.
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.
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 guidelines for choosing carbon adsorbents, physical characteristics of Supelco® carbon adsorbents, adsorbent cross reference

Carbon Molecular sieves (CMS) are a versatile range of adsorbents that can be tailored for specific applications. Supelco® scientists have been synthesizing synthetic CMS carbons for several decades, starting from tailoring of the starting polymers/copolymers, to modifying the final properties of the subsequent CMS carbon.
