Necessity is the mother of Invention


United Science started to engineer carbons for separations purposes in response to a general need for different chromatographic selectivity.  Along the way, we found that naturally derived products can generally not stand up to the rigors of analytical work and that the technology has essentially remained in an unadvanced state for decades.  Even more appalling are the costly poor recoveries, poor stability, questionable chemical reproducibility,  and high equipment maintenance that GCB inflicts on its users.    Behold the engineered carbon for the masses.

CarbonX is available in a wide variety of particle sizes and pore diameters.



  1. Reproducible pore and particle diameter that does not change when in use or when shipped.

  2. Particle sizes from monodisperse HPLC style particles to mesh sizes.

  3. Pore diameters available from 5-300 angstroms.

Mechanical Stability is Important Even for Low Pressure Sample Preparation Applications



  1. GCB is notoriously mechanically friable.

  2. Breaks up in shipping and during use.

  3. Breakage changes surface area and collapses porosity.

  4. Streak test qualitatively compares friabilty.

  5. CarbonX is stable to 10,000 psi plus so it won't break up during use.

Sample Prep Materials



  1. Removes pigments, polar matrix components

  2. Weak pi-pi interactions allow for desorption of planar molecules

  3. Applications include QuEChERS and SPE

Sample Prep Materials



  • Lipid Removal

  • Removes pigments, polar matrix components

  • Weak pi-pi interactions allow for desorption of planar molecules

  • Lewis Base alumina sites interact with lewis base portion of fatty aids.

  • Applications include QuEChERS and SPE
