摘要
报道了一种基于用溶胶凝胶法固定葡萄糖氧化酶（GOD）的化学发光型葡萄糖传感器，此传感器用于流动注射化学发光分析体系,可实现对葡萄糖的在线检测，测定的线性范围为10－1000μmol／L，检出限为0．8μmol／L，10次测定的RSD为1.6％，单次测定能在1min内完成。方法可用于各种食品中葡萄糖含量的测定。
In this paper. a kind of chemiluminescence glucose sensor based on GOD glucose oxidase immobilized by solgel was proposed. With the application of the sensor to flowing injection chemiluminescent system, glucose could be effectively determined with the linear range of its concentration in 10~1000μmol/L and detection limit at 0.8 μ mol/L.A complete analysis could be performed in 1 min with RSD (Relative Standard Deviation) of 1 .6% .The system has been applied successfully to the determination of glucose in various food samples.
