Clean-Up® C4

Hydrophobic extraction sorbents are composed of a silica backbone bonded with hydrocarbon chains. They are used to extract compounds which exhibit non-polar or neutral characteristics from complex matrices. UCT offers a range of hydrophobic sorbents that can be utilized to optimize a variety of separations. Several chain configurations are available as well as endcapped and unendcapped versions.

Clean-Up® C4 - n-Butyl sorbent

  • Organic Loading = 8.5%
  • Average Pore Size = 60Å
  • Surface Area = 500 m²/g
  • Pore Volume = 0.77 cm³/g

Endcapped vs. Unendcapped

Bonded phases are manufactured by the reaction of organosilanes with activated silica. During the polymerization reaction of carbon chains to the silica backbone, a very stable silyl ether linkage forms. Our unendcapped columns allow hydroxyl sites to remain, thus making these columns slightly hydrophilic. In order to decrease this slight polarity, these hydroxyl sites are deactivated. Proprietary bonding techniques ensure that these sites are 100% reacted, leading to a complete endcapping. Because there are no hydroxyl sites left, our endcapped columns are more hydrophobic than our unendcapped columns.
