Sigma-Aldrich offers some of the best adsorbents in the world, led by our highly engineered specialty carbons (Carbotrap, Carbopack, Carboxen, Supelcarb, and Carbosieve). No other materials in the world offer the same adsorption/desorption characteristics as our specialty carbons. We also offer several of the most commonly used molecular sieve and porous polymer adsorbents, allowing access to these materials in various quantities. View our
Adsorbent Selection Guide to find adsorption/desorption characteristics for 15 carbon adsorbents, 5 porous polymer adsorbents, and 4 general purpose adsorbents. This 36 page Technical Report contains 24 easy-to-read color charts, one for each adsorbent.
Adsorbent materials can be used for such diverse applications as collection media for air sampling, packings in gas chromatography (GC) columns and solid phase extraction (SPE) hardware, and for the purification of various gas streams. Their use for these applications is widely published in many methodologies and technical journals.
If you do not see an adsorbent material that fits your exact need, please contact our Technical Service group (
techservice@sial.com) to inquire about our Custom Capabilities. Our very knowledgeable R&D staff has decades of experience engineering specialty carbons for numerous applications. We can also process porous polymers as desired (for example, to remove fines and/or residual monomers).
