T. Hu et al., A screen-printed disposable enzyme electrode system for simultaneous determination of sucrose and glucose, ELECTROANAL, 12(11), 2000, pp. 868-870
A screen-printed disposable enzyme electrode system for the simultaneous de
termination of sucrose and glucose was developed using mediated enzyme reac
tion and screen-printing technology. The system consisted of two carbon wor
king electrodes (electrode I and II) and a Ag/AgCl reference electrode. Chr
onoamperometry was performed on quiescent solutions for the measurement ste
ps se a constant potential of +0.4 V (vs. Ag/AgCl). The enzyme composition
was optimized. The linear response ranges were up to 10 mmol/L sucrose and
15 mmol/L glucose. The sensor was applied to assay real samples. The result
s are in good agreement with those obtained by the reference method.
