Simultaneous determination of bifonazole and benzyl alcohol in pharmaceutical formulations by reverse-phase HPLC
(Springer Heidelberg, Heidelberg, 2005)
A simple, precise and sensitive reverse-phase high performance liquid chromatographic (RP-HPLC) method has been developed for the quantitation of bifonazole, an imidazole antifungal, simultaneously with benzyl alcohol, ...
Chemometrical approach in fosinopril-sodium and its degradation product fosinoprilat analysis
(Springer Heidelberg, Heidelberg, 2004)
In this paper the experimental design has been applied to define the optimum chromatographic conditions for the separation of Fosinopril sodium and its degradation product, fosinoprilat. Fosinopril is a prodrug and after ...
Stability testing of cefuroxime in tablets by micellar liquid chromatography
(Springer Heidelberg, Heidelberg, 2004)
Cefuroxime is a broad-spectrum second-generation bactericidal cephalosporin antibiotic active against beta-lactamose-producing strains. Anti-cefuroxime, the geometric isomer of cefuroxime, might be present in cefuroxime ...
Determination of carvedilol and its impurities in pharmaceuticals
(Vieweg, Wiesbaden, 2005)
A reversed-phase high-performance liquid chromatographic (RP-HPLC) method has been developed for separation of carvedilol and its impurities from Karvileks tablets. The best separation was achieved on a 100 mm x 4.6 mm, 5 ...
Multi-Level Robustness Evaluation Approach: From Robustness Criterion to Adapted Algorithm of Dong
(Springer Heidelberg, Heidelberg, 2013)
This paper proposes an innovative concept for robustness evaluation guided by two crucial aims: indubitable identification of the factors that significantly affect the LC method and avoidance of unnecessary time and money ...
Evaluation of RP-HPLC Method Intended for the Analysis of Cefuroxime Axetil and ITS Impurities Supported by Experimental Design
