詳細
A spherical graphitized polymer carbon (SGPC) has an innovative structure; a porous or non-porous core (the carbon framework that remains after pyrolysis of polymeric precursor), and a graphitized shell of a controlled thickness. 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 amorphous/graphitic adsorbents are:
Generally, SGPC adsorbents offer weaker relative adsorptive strength compared to carbon molecular sieve (CMS) adsorbents, and similar relative adsorptive strength compared to graphitized carbon black (GCB) adsorbents. Our Graphsphere™ products are a type of SGPC adsorbent. They are great alternatives to GCB adsorbents (which are granular and friable).

- Spherical (better packed bed performance than granular particles)
- Hard and non-friable (pack well, will not break)
- Used for molecules with an analyte size relative to C5-C12 n-alkanes
- Hydrophobic (can be used in high humidity environments)

The headspace solid-phase microextraction (HS-SPME) efficiencies from vegetable oil of the recently available Carboxen-poly(dimethylsiloxane) (PDMS) and divinylbenzene-Carboxen-PDMS fibres were found to be much greater than those of the PDMS fibre for a number of volatile contaminants. Using these Carboxen-based fibres

Nine commercial solid adsorbent materials (in order of decreasing surface area: Carboxen 1000, Carbosieve S III, molecular sieve 5A, molecular sieve 4A, silica gel, Carboxen 563, activated alumina, Carbotrap and Carboxen 1016) were investigated for their ability to trap and
