OPQS – optical process and quality sensing : exemplary applications in the beerbrewing and polyurethane foaming processes

Optical methods play an important role in process analytical technologies (PAT). Four examples of optical process and quality sensing (OPQS) are presented, which are based on three important experimental techniques: near-infrared absorption, luminescence quenching, and a novel method, photon density...
