Al-ShaalanProblem statement: The performance characteristics of Sensitive Screen-Printed (SPE) and Carbon Paste (CPE) electrodes were investigated for the Determination of Doripenem (DP) in pure, pharmaceutical preparations and biological fluids. Approach: The proposed electrodes is characterized in terms of plasticizer type, response time, pH and temperature. Results: The two electrodes showed nearly Nernstian behaviours over the concentration range of 2×10−4-5×10−2 mol/l … …American Journal of Pharmacology and Toxicology, Vol. 7, Issue 1 · 21 Feb 2012 · 7,659 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleUtilization of Charge Transfer and Kinetic Methods for the Determination of DoripenemNora H. Al-ShaalanProblem statement: This study presents rapid, uncomplicated and sensitive spectrophotometric techniques for the analysis of doripenem in both its pure and pharmaceutical forms. Approach: The main principle of the approaches and procedures that have been developed is the reaction of doripenem as an n-electron donor to ninhydrin and π-acceptors, such as tetracyanoethylene, 7,7,8,8-tetracyanoquinodimethane, 2,3,5,6-tetrachloro-1,4-benzoquinone, 2,3-dichloro-5,6-dicyano-1,4-benzoquinone and chloranilic acid. The wavelengths … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 10 Feb 2012 · 7,066 accessesView PDFCite
