Process analytic instruments are used in many domains of industry (pharma, food, cosmetics,biotech…) to monitor real-time inline industrial processes. Some benchmark studies on the stability of colloidalparticles in a suspension, show that the mm-W sensor in [1] is 1000 time more sensitive than conventional IRand Raman instruments. Likewise, mm-W sensor can be used for liquid phase composition analysis, for thedrug formulation, etc. Many industrial production companies as end user of mm-W sensor technology wouldbenefit from it by improving product quality and production yield.
