Dispersive Micro-Solid Phase Extraction Combined with High-Performance Liquid Chromatography for the Determination of Three Penicillins in Milk Samples

A simple, rapid, and environmentally friendly microextraction termed COU-2-D-μ-SPE has been developed for the analysis of three penicillins (i.e., oxacillin, cloxacillin, and dicloxacillin) in milk samples. An ordered mesoporous carbon, COU-2, was synthesized and used as the sorbent in dispersive micro-solid phase for the extraction of selected penicillins prior to high-performance liquid chrom...

Separation and determination of synthetic impurities of sildenafil (Viagra) by reversed-phase high-performance liquid chromatography.

A simple and rapid high-performance liquid chromatographic method for the separation and determination of process-related impurities of sildenafil was developed. The separation was achieved on a reversed-phase C18 column using acetonitrile-0.05 M potassium dihydrogen orthophosphate (70:30 v/v) as a mobile solvent at a flow rate of 1.0 ml/min and UV detection at 230 nm. The method was used not o...
