Covalent Sorbent -Thiopropyl
In the case of the aldehyde sorbent, an analyte with a primary amine performs a nucleophilic attack on the aldehyde functionality in the sorbent. This reaction results in a Schiff base, with the amine immobilized on the stationary support. This chemistry can be utilized to bind proteins, such as antibodies, to the support, allowing highly specific extractions.
The thiopropyl functional group scavenges for alkylating agents, alcohols and amines.
