COUTINHO, Cláudia F. B. et al. Development of instrumentation for amperometric and coulometric detection using ultramicroelectrodes. J. Braz. Chem. Soc. [online]. 2008, vol.19, n.1, pp.131-139. ISSN 0103-5053.

In this work it is presented the development of a simple, portable and inexpensive instrumentation for amperometric and coulometric detection in different analytical instrumentation systems utilizing ultramicroelectrodes. The software, developed in LabVIEW 7.1TM, is capable to carry out three main detection techniques (amperometric, pulsed amperometric and coulometric detection) and a voltammetric technique (cyclic voltammetry). The instrumentation was successfully evaluated using the following systems: cyclic voltammograms of metallic electrodes in alkaline solutions, flow electrochemical detection of glucose and glycine and direct determination of herbicide glyphosate (electrochemical detection coupled to HPLC).

Palabras clave : instrumentation; portable; electrochemical detection; ultramicroelectrodes; flow system.
