摘要
计算机控制的微型生物传感器分析系统可以实现生物反应过程中多参数的在线检测 .系统包含在线微量取样、级联稀释、微型生物传感器、生化工程数据处理和分析软件与计算机 .系统实现的指标为取样 10～ 10 0 0 μL/min ,稀释倍数 10 10 .5 4,相对误差小于 2 .5 % ;在线测量酵母发酵的葡萄糖质量浓度 ,最大误差率为 3.88% .
The micro biosensor analysis system can be applied to on line multi parameters identification in bioprocesses. The on line analysis system consisted of a micro flow sampler, a cascade dilution unit, a micro biosensor, a software for bioprocess data processing, and a computer. The flow rate of the sampler ranges fran 10～1 000 μL/min, the relative error was less than 2.5%, and the dilution times were up to 1 010.54. The glucose concentration was determined by the on line micro biosensor during the yeast fermentation, with the maximum relative error of 3.88%.
