Photonic Techniques Pay Big Dividends in Process Control
In industrial processing it pays to know how much of what is in the mix, which is why on-line sampling of both the amount and type of chemical constituents is critical. Only in this way can an operator know whether the mix is correct, or intervention is required. With optical spectroscopy, manufacturers have the potential to perform such analyses with minimal interference to the process flow. For large volume applications, where lost time means lost revenue, this can amount to a huge advantage....
