Application of molecularly imprinted solid‐phase extraction coupled with liquid chromatography method for detection of penicillin G in pasteurised milk samples

Molecularly Imprinted Stir Bar Sorptive Extraction Coupled with High-Performance Liquid Chromatography for Trace Analysis of Diclofenac in Different Real Samples

A novel molecularly imprinted polymer-coated stir bar has been used to selectively extract diclofenac (DFC) directly from real samples. DFC was used as template molecule for preparation of MIP coating. The effect of different parameters on the extraction efficiency were studied and the optimum conditions were established as: the absorption and desorption times were fixed at 10 min, stirring...

Dispersive liquid-liquid microextraction coupled with magnetic nanoparticles for extraction of zearalenone in wheat samples

A new, sensitive and fast dispersive liquid-liquid microextraction (DLLME) coupled with micro-solid phase extraction (μ-SPE) was developed for determination of zearalenone (ZEN) in wheat samples. The DLLME was performed using acetonitrile/water (80:20 v/v) as the disperser solvent and 1-octanol as the extracting solvent.  The acetonitrile/water (80:20 v/v) solvent was also used to extract ZEN f...

molecularly imprinted polymers (mip) for selective solid phase extraction of celecoxib in urine samples followed by high performance liquid chromatography

in this study, for the analysis of human urine samples, a novel method explained for the determination of celecoxib, a nonsteroidal anti-inflammatory drug (nsaid), using molecularly imprinted solid-phase extraction (mispe) coupled with high-performance liquid chromatography (hplc). the synthesis of the mip was performed by precipitation polymerization in methacrylic acid (maa), ethylene glycol ...
