Um experimento de análise em fluxo envolvendo reações enzimáticas e quimiluminescência

Abstract: Recebido em 7/3/03; aceito em 13/8/03A FLOW ANALYSIS EXPERIMENT INVOLVING ENZYMATIC REACTIONS AND CHEMILUMINESCENCE. An experiment is proposed to introduce some fundamentals of flow analysis, chemiluminescence and kinetic monitoring of enzymatic reactions in undergraduate courses. Chemiluminescence detection is performed with a simple spectrophotometer equipped with a lab-made spiral flow cell constructed from a polyethylene tube. The hydrogen peroxide produced by the glucose oxidation in the presence of gluco… Show more

“…This is a critical aspect, because the radiation is emitted in all directions, being necessary to adapt the cell geometry and positioning in relation to the detection system (2). Thus, several cell configurations have been proposed, being usually employed spiral cells, positioned in front of the detection system (3)(4)(5). Campins-Falcó et al (4) evaluated different cell configurations, aiming to improve sensitivity and precision.…”

“…Muitos são os autores [3][4][5][6][7] interessados em elaborar experimentos mais atuais e motivadores, utilizando maneiras diferentes de tratamentos e interpretações de resultados. Mas um curso de licenciatura em Química no período noturno, ainda enfrenta o problema do curto espaço de tempo (3 a 4 h) reservado para uma prática de laboratório.…”
