本文介绍了一种能够连续测量葡萄糖浓度的流动注射分析系统,系统中用来检测葡萄糖的传感器由氧电极和固定化葡萄糖氧化酶膜制成。该系统在16.7ml/min的载体流速下,对葡萄糖浓度的线性测量范围为0.5-25mMol/L,每个样品的测量时间为约40秒,变异系数小于3.2％,传感器可连续使用200次而不需校正,使用寿命在2000次以上。 This article describes a flow injection analysis system that can continuously measure glucose concentrations. The sensors used to measure glucose in the system are made of oxygen electrodes and immobilized glucose oxidase membranes. With a carrier flow rate of 16.7 ml / min, the linear measurement range for glucose concentration is 0.5-25 mMol / L, the measurement time for each sample is about 40 seconds, the coefficient of variation is less than 3.2%, and the sensor can be used continuously for 200 cycles Without correction, the service life of more than 2000 times.
