Optimization of the indirect fluorimetric detection for the simultaneous analysis of inorganic anions and polycharged organic anions by capillary electrophoresis

Abstract: Abstract. Until now, fluorescein sodium salt has been used to generate the background signal for indirect fluorimetric detection of inorganic cations or mono-charged organic anions separated by Capillary Zone Electrophoresis (CZE). In this paper, we extend the use of fluorescein sodium salt to the simultaneous CZE analysis of inorganic anions (Cl

“…This method is only applicable if the metal ion-ligand complex is more stable and does not feel any effect of the experimental CE conditions. Indirect fluorescence detection has further been used in the analysis of metal ions [5,37,38] but this mode of detection has not been used frequently for metal ion speciation in CE. Desbene and Morin [38] have used quinine sulfate as the fluorescence agent for the detection of metal ions using LIF but the detection limit was not good.…”

Desbene and Morin [38] have used quinine sulfate as the fluorescence agent for the detection of metal ions using LIF but the detection limit was not good. Direct fluorescence detection is possible if the ligands used for the analyte complexation reaction contain a chromophore or a fluorophore [39].…”

“…Des premiers résultats sont apparus sur l'analyse des cations alcalins, alcalino-terreux et de métaux de transition complexés négative-ment par l'EDTA en mode de détection indirecte [20][21]. En particulier, les potentialités du sel de sodium de la fluorescéine pour générer le signal de fond ont été prouvées.…”

“…Plusieurs tensioactifs ont été testés avec succès (Tab. III) parmi lesquels le bromure de tétradécylammonium ou TTAB [16][17][21][22][23], le bromure de cétyltriméthylammonium ou CTAB [5], le bromure d'hexaméthonium [10] ou un polymère cationique comme le polybrène [3][4]. D'un point de vue pratique, soit le tensioactif est ajouté au tampon électrophorétique, soit le capillaire est rincé entre deux analyses consécutives.…”

“…The AES oligomers have been separated by HPLC with gradient elution and evaporative light scattering detection [8], and by CE with aqueous (40-50% ACN) [23,24] and nonaqueous BGEs (ACN/MeOH mixtures) [23,33]. Several CE procedures for fatty acids have been also proposed [40][41][42][43][44][45][46][47][48][49][50][51][52][53]. However, the separation of AES and fatty acids in a single electropherogram has not been reported.…”
