ABSORPTION SPECTROSCOPY OF WINDSHIELD WASHER FLUIDS FOR CARS
Annotation
The possibility of using absorption spectroscopy to study the optical properties of windshield washer fluids "Sintech", "Freeze Way", and "Frozox" for cars of different brands is considered. The optical scheme and external view of the measuring instrument, the UV-2600i spectrophotometer, are shown, as well as the measuring block with attached cuvettes for the substance to be analyzed. The obtained spectral absorption curves differ from each other in shape, the observed shifts of the curves are associated with surfactants, functional additives, and dyes.
