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:
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 Carbopack products are a type of GCB adsorbent.

- Granular
- Friable
- Used for molecules with an analyte size relative to C3-C20+ n-alkanes
- Hydrophobic (can be used in high humidity environments)

- Particles are 40 mesh and smaller
- Use 40/60 mesh to prevent channeling (if observed with a 20/40 mesh Carbotrap® adsorbent)
- Use smaller mesh (60/80, 80/100, etc.) for all other applications
- Use the smallest particle size available as long as the application can handle the pressure drop

A selective pressurized liquid extraction technique (SPLE) was developed for the analysis of polychlorodibenzo-p-dioxins, polychlorodibenzofurans (PCDD/Fs) and dioxin-like polychlorobiphenyls (dl-PCBs) in clam and crab tissue. The SPLE incorporated multiple cleanup adsorbents (alumina, florisil, silica gel, celite, and carbopack) within the
