Paper Abstract

The role of on-line chemical analyzers is vital to process monitoring and control and product quality. Although traditional optical filter methods such as UV-VIS, NIR, and IR have enjoyed considerable success when applied on-line, they often require inconvenient and complex sampling schemes. These restrictions can be largely eliminated by fiber optic probes as evidenced by their growing popularity. Fiber optic technology also allows remote location of full spectrum analyzers which in turn facilitates multicomponent analysis. Recently, we have developed a Raman spectrograph which utilizes fiber optic probes and a CCD detector. We have been most successful with this system when it is applied to processes in a short term, investigative role. Examples of reaction intermediates and products, contaminant identification, and process optimization are given.
