Polymer with excellent polarity retention during sample pretreatment |
| abstract |
Provided is a polymer adsorbent that strongly retains a medium to high polarity sample when the sample exists in a complex substrate. Polymeric adsorbents that can be used for extraction and purification of polar and nonpolar molecules by solid phase extraction (SPE) from complex media (eg, pharmaceuticals derived from biological substrates). The present adsorbent exhibits a strong capacity to retain polar molecules, can promote the recovery of compounds having a certain range of polarities, and can provide an extract that does not contain impurities and exhibits low ion suppression. This polymer has wettability and maintains the wet state for a long time. |
