Carboxen® Adsorbents

Carboxen adsorbents:
  • Have through-pore structures (majority of pores pass entirely through particles)
  • Specially designed pores taper from macro- to meso- to micropores, resulting in excellent thermodynamic properties for both adsorption and desorption

No other adsorbents on the market can match their thermodynamic performance. We make sixteen Carboxen adsorbents:
  • Carboxen 563 is useful for collecting volatile organic compounds (VOCs) from water or air.
  • Carboxen 564 is effective for collecting VOCs from air. It has a greater capacity than Carboxen 563.
  • Carboxen 569 is a highly hydrophobic adsorbent, making it useful for sampling in high humidity environments. Relative to Carboxen 563 and Carboxen 564, it has a greater capacity for organic molecules and a lower capacity for water.
  • Carboxen 572 is a highly efficient CMS adsorbent and compares directly to Carboxen 1000. The primary difference between Carboxen 572 and Carboxen 1000 is the particle size distribution (Carboxen 572 is only available in 20/45 mesh whereas Carboxen 1000 is available in 40/60, 60/80, and 80/100 mesh).
  • Carboxen 1000 has a large surface area and optimized microporosity, which enable it to effectively and efficiently adsorb and desorb smaller molecular size compounds, providing excellent chromatography without a need for cryogenic cooling. One of our most efficient CMS adsorbents, it is widely used in purge traps and air sampling media. It is also used for low volume sampling of very volatile compounds, such as vinyl chloride.
  • Carboxen 1001 is used to trap and retain very small compounds. It is often used as the final bed in multi-bed adsorbent tubes, to minimize breakthrough. It is similar to Carboxen 569 in strength and hydrophobicity. Note that bulk Carboxen 1001 adsorbent is only available as a custom item.
  • Carboxen 1003, with a large surface area and hydrophobic surface characteristics, provides a desirable combination of efficient adsorption/desorption and good hydrophobicity.
  • Carboxen 1005 adsorbent is based on Carboxen 1003 adsorbent. With twice the trapping ability compared to active charcoal, it is primarily used in gas purification applications to retain hydrocarbons. Note that bulk Carboxen 1005 adsorbent is only available as a custom item.
  • Carboxen 1006 is only available as 2 μm particles. It is used as an adsorbent in porous layer open tubular (PLOT) capillary GC columns. Note that bulk Carboxen 1006 adsorbent is only available as a custom item.
  • Carboxen 1008 is a washed version of Carboxen 1000, designed for use as an adsorbent in air collection devices. Note that bulk Carboxen 1008 adsorbent is only available as a custom item.
  • Carboxen 1010, only available as 2 μm particles, is used as an adsorbent in PLOT capillary GC columns. Note that bulk Carboxen 1010 adsorbent is only available as a custom item.
  • Carboxen 1012 is a highly activated, inert CMS possessing large mesopores. It can be used effectively for aqueous phase adsorption of organic compounds, or for air sampling of C4-C6 compounds. Note that bulk Carboxen 1012 adsorbent is only available as a custom item.
  • Carboxen 1018, possessing a large percentage of narrow (6-7 Å) micropores, is useful for the adsorption/desorption of small analytes, such as C2 (ethane, ethylene, acetylene) and C3 hydrocarbons. This hydrophobic, inert, and strong adsorbing porous carbon can be used in sampling tubes to collect ethane, acetaldehyde, and other small molecules present in exhaled breath samples. Note that bulk Carboxen 1018 adsorbent is only available as a custom item.
  • Carboxen 1021 is another highly-microporous CMS designed for air sampling of small molecules. It is similar to Carboxen 1018 in that is has a large percentage of small micropores. Compared to Carboxen 1018, it has smaller micropores (5-6 Å), and is more hydrophobic. Note that bulk Carboxen 1021 adsorbent is only available as a custom item.
  • Carboxen 1026 is our most microporous CMS, used as an adsorbent in solid phase extraction (SPE) applications. Note that bulk Carboxen 1026 adsorbent is only available as a custom item.
  • Carboxen 1028 has good mesoporosity, and a narrow particle size range (50-60 μm). Note that bulk Carboxen 1028 adsorbent is only available as a custom item.
