Abstract: The role of on-line chemical analyzers is vital toprocess monitoring and control and product quality.Although traditional optical filter methods such asUV-VIS, NIR, and IR have enjoyed considerable successwhen applied on-line, they often require inconvenientand complex sampling schemes. These restrictions can belargely eliminated by fiber optic probes as evidencedby their growing popularity. Fiber optic technologyalso allows remote location of full spectrum analyzerswhich in turn facilitates multicomponent analysis.Recently, we have developed a Raman spectrograph whichutilizes fiber optic probes and a CCD detector. We havebeen most successful with this system when it isapplied to processes in a short term, investigativerole. Examples of reaction intermediates and products,contaminant identification, and process optimizationwill be given.!34
