Solid-phase extraction of tramadol from plasma and urine samples using a novel water-compatible molecularly imprinted polymer.

In this study, a novel method is described for the determination of tramadol in biological fluids using molecularly imprinted solid-phase extraction (MISPE) as the sample clean-up technique combined with high-performance liquid chromatography (HPLC). The water-compatible molecularly imprinted polymers (MIPs) were prepared using methacrylic acid as… CONTINUE READING
