Raman analysis is not limited to a specific physical form of a material and can be conducted on solids, liquids, and gases. This ability coupled with the non-destructive nature of the technique provides a powerful foundation for implementation within the chemical industry.
Some of the earliest process applications that Kaiser was involved with fall into the category of chemical analysis. Early process successes in the manufacturing environment included titanium dioxide and phosphorous trichloride. These applications are now more than 10 years old with multiyear analyzer uptime running at approximately 98%.
Typical applications for Raman include study of corrosive materials, intermediate formation and control, yield optimization, and end-point detection.
