3 Instrument Specifications

The XDS Process Analytics Instrument uses Near Infrared (NIR) energy to determine chemical and

physical characteristics of the sample. The sample is illuminated with white light through a fiber optic

bundle. The light is returned through a separate fiber bundle path, and the returning signal is broken

down into visible and NIR wavelengths for spectroscopic analysis. The spectroscopic data is processed

using a PC, and results are output in real time. This permits on-the-fly adjustment of the process to

maintain optimum characteristics.

Instrument Specifications are as follows:
