Simultaneous Determination of Two Groups of Elements in Milk by Electrothermal Atomic Absorption Spectrometry: Evaluation of Ruthenium Modifiers
(Perkin-elmer Corp, 2009-09-01)
Different kinds of ruthenium coatings are proposed as chemical modifiers for the simultaneous determination of two groups of elements: first, the more Volatile elements Such as As, Bi, Pb, Sb, and Se and, second, the ...
Spectrophotometric Determination of Captopril Through Charge Transfer Complex Formation Using Fractional Factorial and Central Composite Design
(Colegio Farmaceuticos Provincia de Buenos Aires, 2011-08-01)
A new spectrophotometric method was developed for the determination of captopril (n donor) through charge transfer complex formation with p-chloranil (pi acceptor). The different experimental parameters that affect the ...
A simple and green analytical method for determination of glyphosate in commercial formulations and water by diffuse reflectance spectroscopy
(Pergamon-Elsevier B.V. Ltd, 2011-09-01)
This article describes a simple, inexpensive, and environmentally friendly method for the monitoring of glyphosate using diffuse reflectance spectroscopy. The proposed method is based on reflectance measurements of the ...
Energy efficiency for standard penetration tests
(American Society of Civil Engineers (ASCE), 2005-10-01)
The need for standardization of the measured blow count number N-spt into a normalized reference energy value is now fully recognized. The present paper extends the existing theoretical approach using the wave propagation ...
Determination of the vinylsulphone azo dye, remazol brilliant orange 3R, by cathodic stripping voltammetry
(Elsevier B.V., 1999-04-05)
Remazol brilliant orange 3R shows only a voltammetric peak for the reduction of the azo group. No peak was observed for the reduction of the sulfatoethylsulfone or vinylsulfone reactive groups. The reduction of a pre-protonated ...
The caprine oxyhemoglobin dissociation curve
(W B Saunders Co Ltd, 2006-02-01)
The caprine oxyhemoglobin dissociation curve has not been previously defined. Blood from 10 healthy goats was equilibrated in a tonometer with calibrated gas mixtures of oxygen at concentrations of 95%, 21%, 13%, 12%, 10%, ...
Flow injection amperometric detection of ascorbic acid using a Prussian Blue film-modified electrode
(Elsevier B.V., 2001-08-30)
The PB film-modified electrode was used as an amperometric detector for flow injection analysis of ascorbic acid. The modified electrode detector showed good sensitivity, stability and reproducibility. The calibration curve ...
Determination of methyldopa in pharmaceutical formulations by combined spot test-diffuse reflectance spectroscopy
(2006-08-09)
This paper describes a very simple and rapid quantitative reflectance spot test procedure for the determination of methyldopa in pharmaceutical formulations. This method is based on the complexation reaction of methyldopa ...
High-performance liquid chromatographic determination of amfepramone hydrochloride, mazindol, and diazepam in tablets
(Marcel Dekker Inc, 1999-01-01)
Simple and rapid procedures were developed for the quantification of amfepramone hydrochloride and diazepam and mazindol and diazepam in tablets using high performance liquid chromatography (HPLC) with UV detection. These ...
Quantitation of malondialdehyde in gingival crevicular fluid by a high-performance liquid chromatography-based method
(Academic Press Inc. Elsevier B.V., 2012-04-01)
Lipid peroxidation (LPO) has been associated with periodontal disease, and the evaluation of malondialdehyde (MDA) in the gingival crevicular fluid (GCF), an inflammatory exudate from the surrounding tissue of the periodontium, ...
