A Fast Fluorimetric Flow Injection Method to Determine Ibuprofen
نویسندگان
چکیده
A fluorescência natural da ibuprofeína foi melhorada quando foi formado um complexo convidado-hospedeiro com a beta-ciclodextrina (beta-CD). A partir disso, foi desenvolvido um método por injeção em fluxo para a determinação de ibuprofeína em diferentes preparações farmacêuticas, com detecção fluorescente (λ em 287 nm, λ ex 233 nm). A curva de calibração foi linear no intervalo entre 6,00 a 60,0 mg L de ibuprofeína, com limite de detecção (LOD para S/N=3) de 4,5 mg L. O desvio padrão relativo foi de 1,2% e a velocidade de determinação de 240 amostras por hora. O método foi validado pela comparação do método proposto, e do usado oficialmente, em amostras comerciais preparadas.

Decrease in blood flow and temperature of rat knee joint by calcium
Introduction: The Blood flow increases in the inflamed joint induced by Complete Freund’s Adjuvant (CFA). Since the anti-inflammatory effect of calcium channel blockers have been shown in pervious studies, the present study investigates the role of these blockers on the blood flow and temperature (inflammation indices) in inflamed knee joint induced by CFA. Methods: This experimental study wa...
متن کاملVery Fast Load Flow Calculation Using Fast-Decoupled Reactive Power Compensation Method for Radial Active Distribution Networks in Smart Grid Environment Based on Zooming Algorithm
Distribution load flow (DLF) calculation is one of the most important tools in distribution networks. DLF tools must be able to perform fast calculations in real-time studies at the presence of distributed generators (DGs) in a smart grid environment even in conditions of change in the network topology. In this paper, a new method for DLF in radial active distribution networks is proposed. The ...
متن کاملSpeciation analysis of CrIII–CrVI using flow injection analysis with fluorimetric detection
A relatively simple, sensitive, selective, automatic fluorimetric method for the simultaneous determination of chromium(III) and chromium(VI) by flow injection analysis (FIA) was developed. The method is based on the selective oxidation of the non-fluorescing reagent 2-(a-pyridyl)thioquinaldinamide (PTQA), which with Cr yields an intensely fluorescent product (lex = 360 nm; lem = 500 nm). Chrom...
متن کاملSimulation of Separation of a Racemic Mixture of Ibuprofen by Supercritical Fluid Chromatography in Simulated Moving Bed
Separation of a racemic mixture of ibuprofen at a low concentration level by supercritical fluid chromatography in a simulated moving bed (SFC-SMB) is investigated by simulation. The feasibility of ibuprofen enantiomers separation has been experimentally examined in the literature. Our simulation results show that separation of ibuprofen enantiomers is feasible by this method, and R-ibuprofen a...
متن کاملA microfluidic device with integrated fluorimetric detection for flow injection analysis.
This work describes the development of flow analysis microsystems with integrated fluorimetric detection cells. Channels (width of 300-540 microm and depth of 200-590 microm) were manufactured by deep-UV lithography in urethane-acrylate (UA) resin. Plastic optical fibers (diameter of 250 microm) were coupled to a 2.0-mm-long detection channel in order to guide the excitation radiation from an L...
