Fast Determination of Ciclopirox in Pharmaceutical Products by Amperometry in Flow and Batch Injection Systems
(WILEY-V C H VERLAG GMBHWEINHEIM, 2012)
Amperometry coupled to flow injection analysis (FIA) and to batch injection analysis (BIA) was used for the rapid and precise quantification of ciclopirox olamine in pharmaceutical products. The favourable hydrodynamic ...
Determination of sulfate in ethanol fuel using an electrode chemically modified with polypyrrole by flow injection analysis
In this work, an electrode chemically modified with polypyrrole (PCME) was employed for determination of sulfate in ethanol fuel using a FIA system. The PCME was prepared by polymerization of pyrrole at a glassy carbon ...
Development of a potentiometric flow cell with a stainless steel electrode for pH measurements. Determination of acid mixtures using flow injection analysis
(Elsevier Science BvAmsterdamHolanda, 2000)
Use of a carbon paste electrode modified with spinel-type manganese oxide as a potentiometric sensor for lithium ions in flow injection analysis
A potentiometric sensor constructed from a mixture of 25% (m/m) spinel-type manganese oxide (lambda-MnO2), 50% (m/m) graphite powder and 25% (m/m) mineral oil is used for the determination of lithium ions in a flow injection ...
Flow-injection spectrophotometric determination of methyldopa in pharmaceutical formulations
(Elsevier B.V., 2005-07-15)
A flow-injection spectrophotometric procedure is proposed for methyldopa determination in pharmaceutical preparations. The determination is based on formation of a yellow product (measured at 410 nm) after complexation of ...
Flow injection method for preconcentration and polarographic determination of copper in water
(WILEY-V C H VERLAG GMBH, 2000-03)
The analytical application of a simple polarographic Row through cell, which was previously designed for the continuous polarographic analysis of organic compounds in pharmaceuticals and urine, is proposed in this work for ...
TURBIDIMETRIC DETERMINATION OF POTASSIUM BY FLOW-INJECTION ANALYSIS
(Marcel Dekker IncNew York, 1994)
Rapid determination of zinc in foods by flow injection analysis with flame AAS using gradient calibration method
A calibration method was developed using flow injection analysis (FI) with a Gradient Calibration Method (GCM). The method allows the rapid determination of zinc In foods (approximately 30 min) after treatment with ...
Characterization of proanthocyanidins from Parkia biglobosa (Jacq.) G. Don. (Fabaceae) by flow injection analysis - Electrospray ionization ion trap tandem mass spectrometry and liquid chromatography/electrospray ionization mass spectrometry
The present study investigates the chemical composition of the African plant Parkia biglobosa (Fabaceae) roots and barks by Liquid Chromatography - Electrospray Ionization and Direct Injection Tandem Mass Spectrometry ...
