Application of Infrared Spectroscopy to Monitoring the Bioprocesses
红外光谱技术在生物过程监测中的应用

On line measuring concentrations of chemical components is of fundamental importance in many bioprocesses.However,the on line measurement is very difficult to make for many analytical techniques because of the requiring sterilization of probes and the complexity of the bioprocesses.Rapid advances in instrumentation and data processing techniques in recent years have allowed infrared spectroscopy to be increasingly applied to in situ or on line monitoring bioprocesses.The basic principle and recent developments of infrared process analysis are introduced .In addition,the application of infrared spectroscopy in monitoring bioprocesses are reviewed.
