A system based on fiber spectrometer was designed to detect the concentration of various artificial pigments contained in the solution. Using this system, the absorbance curves of five kinds of artificial colors of lemon yellow, sunset yellow, carmine, bright blue and amaranth were measured, and the absorption coefficient of each pigment at different wavelengths was calculated. The reliability of...
In order to conveniently measure the concentration of artificial pigments in different solutions, a portable measurement system was developed based on miniature fiber optic spectrometer (MFOS). With this system, the absorbance curves and the absorption coefficients in the visible band for five kinds of artificial pigments in different solutions were measured and calculated. By measuring the concentration...
