First-order UV-derivative spectrophotometry in the analysis of omeprazole and pantoprazole sodium salt and corresponding impurities
(Pergamon-Elsevier Science Ltd, Oxford, 2003)
The first-order UV-derivative spectrophotometry, applying zero-crossing method was developed for the determination of omeprazole (OM), omeprazole sulphone (OMS), pantoprazole sodium salt (PANa), and N-methylpantoprazole ...
Determination of bifonazole in creams containing methyl- and propyl p-hydroxybenzoate by derivative spectrophotometric method
(Pergamon-Elsevier Science Ltd, Oxford, 2003)
A second order derivative spectrophotometric method for the determination of bifonazole in the presence of methyland propyl p-hydroxybenzoate as preservatives has been developed. The determination was performed in a 0.1 M ...
UV-densitometric determination of maprotiline, desipramine and moclobemide in pharmaceutical dosage forms
(Vieweg, Wiesbaden, 2003)
Maprotiline, desipramine and moclobemide are widely used in the treatment of depression. The content of these antidepressants in bulk drug and pharmaceutical formulations were determined by TLC and in situ densitometry ...
The use of limiting currents in determination of the effect of viscosity in electrochemical experiments performed in mixtures of water with some organic co-solvents
(Elsevier, 2003)
Abstract
Ratios of limiting diffusion controlled currents recorded in aqueous solutions to those obtained in mixture with water-soluble organic co-solvents yield values of ηrel1/2. These values can be used for evaluation ...
Adsorptive stripping voltammetric determination of cefetamet in human urine
(Elsevier, 2003)
Abstract
On the basis of previously established mechanism of cefetamet (CEF) reduction, two methods were suggested for
CEF determination*/differential pulse polarographic and differential pulse adsorptive stripping ...
