Carbon Adsorbent Kits

sigma-aldrich.com/supelcoCarbon Adsorbent Kits Having trouble finding the proper carbon adsorbent for the innovative application you’re developing?Try a Carbon Adsorbent Sampler Kit from SupelcoOften choosing the right adsorbent or combination of adsorbents can be difficult. The goal in selecting the proper adsorbent is to choose one or more that can retain a specific analyte, or group of analytes, for a specific sample volume. However, equally important is that the adsorbent(s) must also be able to release the analyte(s) during the desorption process.By using one of the Supelco Carbon Adsorbent Sampler Kits, the method developer obtains a cost-effective way to evaluate several carbon adsorbents when designing adsorbent-based applications and products. Once the appropriate material has been identified, Supelco is ready to work with you to produce larger quantities to your specifications.2,3,7,8-Tetrachlorodibenzo-p-dioxinGraphitized Carbon Black (GCB)Unlike activated charcoals, which are porous, graphitized carbon blacks (GCBs) generally are non-porous. Consequent-ly, the entire surface of these materials is available for interactions that depend solely on dispersion (London) forces. Since we prepare our GCBs at temperatures >2500 °C, the high purity nature of the resulting carbon material ensures effective release/desorption of the analytes of interest. Carbotrap signifies material that is larger than 40 mesh (e.g. 20/40), whereas Carbopack signifies material that is smaller than 40 mesh (e.g. 60/80).Carbon Molecular Sieve (CMS)A carbon molecule sieve (CMS) particle is the carbon skeletal framework remaining after the pyrolysis of a poly-meric precursor. These materials are primarily used for collecting very small molecular-sized compounds (C2-C5). The size and shape of the analyte molecule and the size and shape of the pores in the CMS particle determine how well the analyte is adsorbed and desorbed. Since our CMSs are prepared from high purity polymers, the resulting material is a high purity carbon material, effective in the release/desorp-tion of adsorbed analytes for quantification.Related ProductsSupelco offers a wide range of empty glass or stainless steel tubes for thermal desorption, polypropylene tubes for solid phase extraction, and other accessories necessary to pack your own tubes. Please refer to the Supelco catalog or visit our web site sigma-aldrich.com/supelcoGeneral Guidelines for Choosing Carbon AdsorbentsFor multi-bed tubes, use the weaker adsorbent in front of the stronger adsorbent. For example, use Carbopack C in front of Carbopack B.

Consider all atoms, not just Carbon. For example, even though 1,2-Dichloroethane is a C2, the two Chlorine atoms give it a relative size between C4 and C5.Related InformationFor more in-depth information, visit sigma-aldrich.com/supelco, and view T402025, “A Tool for Selecting an Adsorbent for Thermal Desorption Applications” which includes adsorption/desorption data on 43 common air pollutants on 24 different adsorbents, and T402026, “Characterization of Adsorbents for Sample Preparation Process” which describes the past, present, and future of carbon adsorbent research at Supelco.Application AssistanceNeed help determining which kit best suits your application?

This effort has been critical to the advancement of chromatography products like GC columns and sample preparation products. Today Supelco has over 87 different carbons ranging in particle size from 1-1000 microns and surface areas from 1-1500m2/g. Our efforts have been broad in scope, and have ranged from purification process development to research focusing on the thermodynamic and kinetic properties of adsorbents. Understanding the performance characteristics of adsorbents has been our primary goal.The unique and valuable characteristics of the Supelco carbons warranted their inclusion in experiments on the 1995 Galileo Mission to Jupiter and the 2005 Cassini-Huygens Mission to Titan, Saturn’s largest moon. Supelco carbons will make their next venture into space with the 2007 Mars Mission.Accelerating Customers’ Success through Leadership in Life Science, High Technology and Service.The SIGMA-ALDRICH Group® ®™©2006 Sigma-Aldrich Co.
