A parallel chiral/achiral LC–MS/MS assay has been developed and validated to measure the plasma and urine concentrations of the enantiomers of ketamine, (R)- and (S)-Ket, in complex regional pain syndrome (CRPS) patients receiving a 5-day continuous infusion of a sub-anesthetic dose of (R,S)-Ket. The method was also validated for the determination of the enantiomers of the Ket metabolites norketamine,...
Uniformly-sized, molecularly imprinted polymers (MIPs) for (S)-nicotine have been prepared by a precipitation polymerization method using methacrylic acid (MAA) or 2-(trifluoromethyl)acrylic acid (TFMAA) as a functional monomer and divinylbenzene (DVB) as a cross-linker in a mixture of toluene and acetonitrile. The (S)-nicotine-imprinted MAA-co-DVB polymers were monodispersed microspheres of about...
