Spectrophotometric determination of midazolam in pharmaceutical formulations
(Journal of Pharmaceutical and Biomedical Analysis, 1995)
Application of artificial neural networks in HPLC method development
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
The use of artificial neural networks (ANNs) for response surface modelling in HPLC method development for amiloride and methychlothiazide separation is reported. The independent input variables were pH and methanol ...
HPTLC determination of ceftriaxone, cefixime and cefotaxime in dosage forms
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
The objective of this investigation was to develop a HPTLC method for the determination of ceftriaxone, cefixime and cefotaxime, cephalosporins widely used in clinical practice, High performance TLC of cephalosporins was ...
Determination of fleroxacin in human serum and in dosage forms by derivative UV spectrophotometry
(Pergamon-Elsevier Science Ltd, Oxford, 1998)
Densitometric determination of metoprolol tartrate in pharmaceutical dosage forms
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
This paper describes a simple densitometric method for the determination of metroprolol tartrate in tablets and ampoules. After separation on silica gel GF254 plates, using acetone-methanol-triethylamine as the mobile phase ...
Statistical optimization of a reversed-phase liquid chromatographic method for the analysis of amiloride and hydrochlorothiazide in tablets
(Pergamon-Elsevier Science Ltd, Oxford, 2000)
A method has been developed for the separation of hydrochlorothiazide and amiloride by high-performance liquid chromatographic (HPLC) method on a C-18 column with detection at 280 nm. The optimal conditions of separation ...
Fluorodensitometric determination of conjugated estrogens in raw material and in pharmaceutical preparations
(Elsevier, 1989)
A simple, rapid and reproducible fluorodensitometric method for the determination of conjugated estrogens has been developed. The proposed procedure includes the following steps: extraction, hydrolysis of sodium sulphate ...
Gas chromatography mass spectrometry determination of isosorbide 5-mononitrate and related impurities in raw materials and dosage formulations
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
A straightforward quantitative method for gas chromatography-mass spectrometry determination of isosorbide 5-mononitrate (ISSMN) and its related impurities such as isosorbide (IS), isosorbide diacetate (ISDA) and isosorbide ...
Spectrophotometric determination of desoximetasone in ointment using 1,4-dihydrazinophthalazine
(Pergamon-Elsevier Science Ltd, Oxford, 1996)
The proposed method is based on coloured hydrazone formation with 1,4-dihydrazinophthalazine as a reagent. Heating at 85 degrees C for 2 h was found necessary to ensure optimal hydrazone formation in the presence of ...
Development of liquid chromatographic method for the analysis of dabigatran etexilate mesilate and its ten impurities supported by quality-by-design methodology
(Elsevier Science BV, Amsterdam, 2015)
In this paper, the development of reversed-phase liquid chromatographic method for the analysis of dabigatran etexilate mesilate and its ten impurities supported by quality by design (QbD) approach is presented. The defined ...
