Dye, Diethylene Glycol, Water, and Surfactant Content in Ink
13 Jul 2017This Application Note shows how Vis-NIR spectroscopy can be used to quantify four important parameters – dye, diethylene glycol (DEG), surfactant and water content – of the ink industry. The determination of these parameters, commonly achieved using time-consuming wet chemistry methods, can be replaced by VisNIR spectroscopy. The latter measures all parameters of interest in a single measurement and can be performed even by untrained users.
