摘　　要：生物发酵工程是获取生物技术产品的主要手段,是一个非常复杂的系统,其产品产量与质量受培养过程中各种参数变化的影响,对发酵过程进行实时、在线的监测是非常必要的。针对发酵过程设计了一种用于生物过程的红外在线分析仪,在一种具有紧凑结构的干涉仪的基础之上,利用摆动式的动镜系统提高系统分辨率与信噪比,并且设计了一种能够直接插入到生物反应器之中的衰减全反射式的探头。通过对仪器基本性能的测试以及在线实验的检验,表明仪器的性能稳定可靠,能够快速、准确的对生物过程进行定量分析。Biological fermentation engineering is the main means of biotechnology products,and it’s a very complex system engineering.There are many factors that affect the quantity and quality of the products.Real time and in-line monitoring of the fermentation process is very necessary.An infrared in-line analyzer is designed for the fermentation process.Based on a compact interferometer,a swing moving mirror system is designed,and a kind of ATR probe is designed.The results of off-line and in-line experiments indicate that the performance of the analyzer is stable and reliable,the quantitative analysis for biological process can be operated rapidly and accurately.
