Flow injection biamperometric determination of captopril
(Elsevier Science, 2002-09)
An automated method to determine captopril (1-[(2S)-3-mercapto-2-methylpropionyl]-L-proline) is proposed. A flow injection manifold based on the indirect biamperometric detection of the captopril by using Fe(III)/Fe(II) ...
Fast spectrophotometric determination of fluoride in ground waters by flow injection using partial least-squares calibration
(Elsevier Science, 2004-06)
The presence of sulphate constitutes a serious interference in the usual zirconium lake-based spectrophotometric method for the determination of fluoride in water. In this report, full spectral data have been recorded for ...
Amperometric flow injection analysis as a new approach for studying disperse systems
(Pergamon-Elsevier Science Ltd, 2009-12)
Fast and simple quantitative determination in dispersed systems (layered double hydroxides - LDHs - suspensions in aqueous solutions) was performed by a procedure that couples flow injection and amperometric detection ...
Determination of As(III) in nonacidified groundwater samples for inorganic speciation analysis using flow injection hydride generation atomic absorption spectrometry
(Taylor, 2010-08)
A flow injection system coupled to hydride generation atomic absorption spectrometry with heated quartz tube atomizer was employed for the selective determination of As(III) in real groundwater samples under nonacidic ...
Novel strategy for fluorescence determination of glibenclamide in samples with high concentration of caffeine based on a low-pressure flow injection chromatography system
(Elsevier Science, 2018-11-07)
In this work, a new low-pressure flow injection chromatography (FIA-C) system with fluorescence detection was developed for the toxicological control of glibenclamide in beverages with high caffeine content. As caffeine ...
A simple method to quantify azo dyes in spices based on flow injection chromatography combined with chemometric tools
(Association of Food Scientists and Technologists of India, 2021-10-27)
Para Red (PR) and Sudan dyes have been illegally used as colorants to adulterate certain foods by enhancing their red/orange colour. In addition, they are toxic and carcinogenic. This work presents the development of a ...
On-line adsorption/preconcentration using a knotted reactor for total Hg determination in drinking water by flow injection CV-AAS
(Perkin-Elmer Corporation, 2001-05)
An on-line mercury pre-concentration and analysis system using atomic absorption spectrometry (AAS) and flow injection (FI) with cold vapor (CV) generation was studied. The mercury was retained as a mercury-2-(5-bromo-2- ...
Flow Injection-Traveling-Wave Ion Mobility-Mass Spectrometry for Prostate-Cancer Metabolomics
(American Chemical Society, 2018-11)
Flow injection-traveling-wave ion mobility-mass spectrometry (FITWIM-MS) was applied to the nontargeted metabolic profiling of serum extracts from 61 prostate-cancer (PCa) patients and 42 controls with an analysis speed ...
Stokes flow paths separation and recirculation cells in X-junctions of varying angle
(American Institute of Physics, 2012-02)
Fluid and solute transfer in X-junctions between straight channels is shown to depend critically on the junction angle α in the Stokes flow regime. Experimentally, water and a water-dye solution are injected at equal flow ...
On-line preconcentration and determination of chromium in parenteral solutions by flow injection - Flame atomic absorption spectrometry
(Elsevier Science, 2003-02)
An on-line chromium preconcentration and determination system implemented with flame atomic absorption spectrometry (FAAS) associated to flow injection (FI) was studied. For the retention of chromium, 4-(2-Thiazolylazo)-resorcinol ...
