Cleanert PEP-2

Cleanert® PEP-2 is made of polydivinylbenzene on which the surface is functionalized with vinyl pyrrolidone and urea. In addition to a balanced hydrophilic and hydrophobic property, the PEP-2 is also an electron donor in a polar-polar interaction, as well as a strong hydrogen donor and acceptor in hydrogen bonding. As a result, the PEP-2 can retain most of acidic, basic and neutral polar compounds without adjusting the pH of the samples. PEP-2 has stronger retention of polar compounds than PEP.
