Monomer recovery Subject

The selective extraction of catecholamines has been the subject of some studies [250,269]. Recently B. Claude et al developed a method for the selective SPE of catecholamines and metanephrines from bovine serum using MIPs, and reported the recovery, RSD and linearity range of the method to be in the orderof64-98%, less than 6% and 0.30-0.90 pM respectively [250]. In another study M. Bouri et al reported the selective extraction of catecholamines from urine using a dopamine MIP coated magnetic molecularly imprinted polymer and capillary electrophoresis. They used methacrylic acid as the monomer, ethylene glycol dimethacrylate as the cross-Unker and coated the MIP on FCjO particles and used 2,2 - azobisisbutyronitrile as the initiator in methanol/water or acetonitrile/water solvents, and reported LOD of 0.04-0.06 pM, RSD of 0.7%-1.4% and a response range of 2.9%-5.5% [269].
