Determination of oxalate by FIA with electrogenerated chemiluminescence detection.

Flow-injection chemiluminescence and electrogenerated chemiluminescence determination of escitalopram oxalate in tablet form.

Rapid, simple and highly sensitive flow-injection (FI) chemiluminescence (CL) and flow-injection electrogenerated chemiluminescence (ECL) methods were developed for the determination of escitalopram oxalate (ESC), a selective serotonin reuptake inhibitor used as an antidepressant drug. The CL method was based on the CL reaction of ESC with acidic cerium(IV) and tris(2,2'-bipyridyl)ruthenium(II)...

Electrogenerated chemiluminescent determination of oxalate.

Determination of sulpiride by capillary electrophoresis with end-column electrogenerated chemiluminescence detection.

BACKGROUND Capillary electrophoresis (CE) with tris(2,2'-bipyridyl)ruthenium(II) [Ru(bpy)3(2+)]-electrogenerated chemiluminescence (ECL) detection is a promising method for clinical analysis. In this study, a method combining CE with Ru(bpy)3(2+) ECL (CE-ECL) detection that can be applied to amine-containing clinical species was developed, and the performance of CE-ECL as a quantitative method ...

Determination of Chloramphenicol in Tablets by Electrogenerated Chemiluminescence

O antibiótico cloranfenicol foi determinado em drágeas por quimiluminescência eletrogerada acoplada a sistemas FIA utilizando-se como espécie luminescente o complexo Ru(bipi) 3 . O cloranfenicol provoca um decréscimo na intensidade luminescente do complexo de rutênio que é proporcional à concentração sendo linear entre 5 x 10 e 1 x 10 mol L. Para 12 medidas sucessivas o desvio padrão relativo o...

Electrogenerated chemiluminescence. 58. Ligand-sensitized electrogenerated chemiluminescence in europium labels.

The electrochemistry and electrogenerated chemiluminescence (ECL) of a series of europium chelates, cryptates, and mixed-ligand chelate/cryptand complexes were studied. The complexes were of the following general forms:  EuL(4)(-), where L = β-diketonate, a bis-chelating ligand (such as dibenzoylmethide), added as salts (A)EuL(4), where A = tetrabutylammonium ion or piperidinium ion (pipH(+)); ...
