In this paper high-performance liquid chromatography with diode array UV detection (HPLC/DAD) after SPE sample pretreatment for simultaneous analysis of pharmaceuticals from three different classes: enrofloxacin, oxytetracycline and trimethoprim, has been developed, optimised and validated. The chromatographic separation was developed on spiked wellspring water samples and checked on model wast...

The purification of endohedral metallofullerenes by high performance liquid chromatography is very time-consuming and expensive. A number of rapid and inexpensive non-chromatographic methods have thus been developed for large-scale purification of metallofullerenes. In this review, we summarize recent advances in non-chromatographic purification methods of metallofullerenes. Lewis acid-based co...

Chromatography has developed from an analytical technology to a well-established separation process in industry. It is the method of choice for difficult separation tasks especially when temperature-sensitive components or species exhibiting very similar thermodynamic properties are involved. Large-scale industrial applications have been reported from different industrial fields, e. g. in the p...

The combination of Atorvastatin and Losartan was used in the management of Hypertension. The present work was focused on the development of RP-HPLC method for the estimation of Atorvastatin and Losartan in binary mixtures by internal standard method. The separation was performed on LUNA C18 column at 238 nm by isocratic elution using Telmisartan as internal standard. Methanol and phosphate buff...
