Cleanert PEP-2

Summary

Cleanert PEP-2 is made of polydivinylbenzene on which the surface is functionalized with vinyl pyrrolidone and urea.

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.

Particle Characteristics

Suggestion Processing Method

Good Water-Wettability

The Cleanert PEP-2 (polar polymer) sorbent is a unique hydrophilic-lipophilic balanced material. It provides excellent wettability since the hydrophobic surface of the sorbent is highly modified with polar functional groups. The SPE mechanism follows the reversed phase separation principle.

High Retention for Polar Compounds and Acid Compounds
The electron donating and with-drawing functionalities of the sorbent allow it to have enhanced retention for polar compounds. For high polar compounds such as acid analytes, there is no need to adjust the pH condition to restrain the ionization of the target analytes, which make method more simple and robust.
