A simple and reliable new HPLC method with UV detection has been developed and validated for simultaneous determination of mitotane and its two metabolites DDA and DDE. Method development was carried out utilizing systematical ...
Optimization of TLC method for separation and determination of ziprasidone and its impurities
(Taylor & Francis Inc, Philadelphia, 2016)
A thin-layer chromatographic method for simultaneous determination of ziprasidone and its main impurities was developed and validated. Separation of the examined compounds was performed on chromatographic plates precoated ...
Forced degradation study of torasemide: Characterization of its degradation products
(Taylor & Francis Inc, Philadelphia, 2013)
Torasemide was subjected to forced degradation studies. Stress conditions were varied concerning hydrolysis (acid, base, and neutral), oxidation, photolysis, and thermal degradation in order to identify the potential ...
Optimization of Chromatographic Separation of Acetylsalicylic Acid, Amlodipine, Impurity a of Amlodipine, and Atenolol in Hydrophilic Interaction Liquid Chromatography Employing DoE Methodology
(Taylor & Francis Inc, Philadelphia, 2015)
The retention behavior of substances in hydrophilic interaction liquid chromatography (HILIC) is difficult to predict. Mixture investigated in this paper consists of acetylsalicylic acid, amlodipine, impurity A of amlodipine, ...
Optimization of an RP-HPLC method for drug control analysis
(Marcel Dekker Inc, New York, 2003)
Optimization of important conditions for the reversed-phase high-performance liquid chromatographic method was done for the separation of the active ingredients in Marcaine(R) adrenaline injections (bupivacaine hydrochloride ...
Determination of Moclobemide and its Metabolites in Human Plasma by SPE-HPLC-UV: Evaluation of Critical Experimental Conditions and QSRR Study
(Taylor & Francis Inc, Philadelphia, 2009)
A SPE-HPLC-UV method for determination of moclobemide and its major metabolites, Ro 12-5637 and Ro 12-8095, in human plasma had been developed previously and its selectivity was evaluated against the most frequently ...
An Experimental Design Approach to Selecting the Optimum HPLC Conditions for the Determination of 2-Arylimidazoline Derivatives
(Taylor & Francis Inc, Philadelphia, 2009)
