G10: Functional dyes and related materials
JASCO FTIR 6300 spectrometer
The spectrometer can be used for: Measurement in transmission (in KBr pellets, liquids and gases in specific cells); Total attenuated reflectance (ATR-FTIR) – Analysis of liquids, pastes, powders, films and flexible solids; FTIR specular reflectance – Measurement of liquid surfaces, thin films, thin layers of creams, pastes with double transmission on absorption test cards; thickness of plastic films, measurement of films on metal substrates; Diffuse Reflectance (DRIFT) – Analysis of powders, rough surfaces and fibers in mixtures with KBr; dilution-free analysis using an abrasive sampling kit; 80 degree angle reflection for thin film characterization.
JASCO V570 UV-VIS-NIR spectrophotometer
The spectrophotometer is used to measure: a) Absorbance or transmittance of a sample in the UV-VIS-NIR range; b) Film thickness calculation based on transmission and reflection spectra of thin films ; c) Transmittance of liquid and solid samples; d) Reflectance of solid samples; color analysis (tristimulus values, chromaticity coordinates, lightness, hue, chroma, color differences based on the XYZ Color System – CIE); e) Solar Direct Transmittance/reflectance measurement – calculates the transmittance and reflectance of both solar radiation and visible light ; f) Analyze thin films on planar surfaces.
JASCO FP6500 spectrofluorimeter
Spectrofluorimeter is used for: a) Recording emission and excitation fluorescence spectra on powders, films and liquids; b) Color fluorescence measurement – measures the reflectance (% R) of a fluorescent sample and calculates the tristimulus values, chromaticity coordinates, brightness index and chromaticity index according to the XYZ color specification system established by CIE; b) Calculation of the solid state quantum efficiency in the fluorescence emission spectrum using the standard reflectance spectrum and the emission spectrum of the sample (using an integrating sphere – ISF 513).
