AN-NIR-026
Dye, diethylene glycol, water and surfactant content in ink
Summary
Ink is a complex mixture that, along with numerous additives, is comprised mainly of solvent, dye, water and surfactant. Vis-NIR spectroscopy is outstandingly suitable for providing rapid and reliable determinations of constituents in the context of quality controls. This Application Note describes the determination of diethylene glycol (DEG), water, dye and surfactant.
