Preparation of Paper Coatings
Paper coatings impart a variety of properties, both decorative (whiteness, opacity etc.) and functional (smoothness, absorption rate etc.) A typical coating has two principal constituents: a dispersion of pigments in water and an adhesive or binder. Traditionally coatings were based on clays

weight and solids content. The powerful TurnDry drying method does an excellent job of eliminating color absorption into the base sheet: the coating color will be completely immobilized within half a second after coating. Thus, the base paper between the wet coating layers, has no time to wet too

Detection of Volatile Organic Compounds (VOC's) with a Spectrally Filtered Cooled Mid-Wave Infrared Camera
proximity with pipes, valves and other VOC carrying components. It is also easy to miss a leak as the devices give only an indication of a leak, but no image. This paper will describe new infrared imaging technology that uses a special infrared imager employing a sensitive detector and a cold filter

Tangential Flow Filtration
to optimize the process. Permeate Line. Either an optek TF16 turbidimeter, or an AF45 or AF46 UV absorption sensor is typically used to monitor the permeate line. With an optek sensor installed on your permeate line you can identify trace containments under 1ppm and detect filter breakthrough in real-time

Produced Water Monitoring (.pdf)
Due to the non-availability of Freon, there is need for an alternative method to measure the concentration of hydrocarbons in the effluent today. Current methods use solvent extraction and IR analysis of water samples. In this paper we present an alternative method, which does not use any solvents
