[Molecularly-imprinted solid phase extraction coupled with high performance liquid chromatography for the determination of ractopamine in feed samples]
{{output}}
Molecularly imprinted polymers (MIPs) with high selectivity to ractopamine (RAC) were prepared by using RAC as template, acrylamide (AM) as monomer, and ethylene glycol dimethacrylate (EGDMA) as cross-linker. The effects of four porogens (methanol, acetonitril... ...
