The Glutamate Biosensor and Its Application to Flow Injection Analysis System
谷氨酸传感器及在流动注射分析中的应用

An enzyme electrode was prepared by cross-linking the L-glutamate oxidase with glutar-aldehyde on an aminopropyl-platinized-platinum wire. It was used for the determination of L-glutamate in a flow injection analysis system. The peak current is linearly related to the L-glutamate concentration in the range 0-2.0 mmol/L, with good performance: accuracy (CV = 0. 4%), fast response (<60sec), stability (> 20 days).
