A Fully Automated Sequential-Injection Analyser for Dual Electrogenerated Chemiluminescence/Amperometric Detection

Comparison between Amperometric and Chemiluminescence methods in detection and dosimetry of cobalt-60 gamma ray emission

Background: Hydrogen peroxide (H2O2), produced by gamma ray irradiation to watery solution, was used as an analytical parameter for dosimetry of cobalt-60 (60Co) radiation. Materials and Methods: Detection of the produced H2O2 was carried out using two methods: an amperometric biosensor fabricated by immobilization of anthraquinone 2-carboxylic acid modified horseradish peroxidase on glassy car...

Automated analysis of the serum antioxidative activities against five different reactive oxygen species with the sequential injection and chemiluminescence detection methods

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)...

Fully Automated Quantification of Insulin Concentration Using a Microfluidic-Based Chemiluminescence Immunoassay.

A fully automated microfluidic-based detection system for the rapid determination of insulin concentration through a chemiluminescence immunoassay has been developed. The microfluidic chip used in the system is a double-layered polydimethylsiloxane device embedded with interconnecting micropumps, microvalves, and a micromixer. At a high injection rate of the developing solution, the chemilumine...

Flow-injection chemiluminescence determination of isoniazid using on-line electrogenerated BrO2 as an oxidant

By designing a novel electrolytic flow cell, the strong oxidant BrO2 was electrogenerated on-line in KBr solution and its concentration could be readily adjusted on-line with the flow-injection technique and an electrochemical method. The chemical reaction between BrO2 and luminol in alkaline medium is accompanied by weak emission of light due to chemiluminescence (CL). It was found that the is...
