A new, rapid, economical and isocratic reverse phase high performance liquid chromatography (RP-HPLC) method was developed for the determination of eptifibatide acetate, a small synthetic antiplatelet peptide, in bulk drug substance and pharmaceutical dosage forms. The developed method was validated as per of ICH guidelines. The chromatographic separation was achieved isocratically on C18 colum...

The power of traditional high-performance liquid chromatography with UV detection (HPLC-UV, DAD) can be readily extended by simply coupling a mass spectrometer (MS) to an existing system. In the early years of liquid chromatographic mass spectrometry (LC-MS), this coupling was considered exotic and complex. After more than 15 years of refinement, LC-MS systems are robust and easy to use, and pr...

a solid-phase extraction (spe) method for sample clean-up and preconcentration followed by reversed-phase high-performance liquid chromatography (rp-hplc) with uv detection is reported for determination of polycyclic aromatic hydrocarbons (pahs) in the caspian seawater. a good resolution was obtained using acetonitrile:water (40:60) as mobile-phase for separation of these compounds. the effect ...

A simple, rapid and sensitive method termed as magnetic solid phase extraction (MSPE) combined with high-performance liquid chromatography-ultraviolet detector (HPLC-UV) has been proposed for the determination of trace amounts of chlorpromazine (CPZ) in water, urine and plasma samples. The separation and determination was performed on a C18 column under the optimal chromatographic conditions. S...

Determination of sildenafil by various methods and in various media is reviewed in this paper. The methods used consist of ultraviolet (UV) spectroscopy, thin layer chromatography (TLC), and high-performance liquid chromatography (HPLC). These methods were used to determine the amount of sildenafil in pharmaceutical preparations, soft drinks, and biological liquids. HPLC was used for evaluation...

Owing to the efficacy and popularity of anastrozole in the treatment of estrogen receptor-positive breast cancer, interest in analytical methods for its quantitative measurement both in pharmaceutical dosage formulations and Biological samples has risen sharply for a decade. This paper reviews the existing chromatographic methods, which are based on two popular detection methods: high performan...
