Analysis of Discoloration and Coloration Using FTIR and EDX

With just minor discoloration which is now a sufficient reason for complaint, it is no easy task for manufacturers to investigate root cause of discoloration from a wide range of possibilities and pinpoint the correct one. When the quantity of material causing discoloration or coloration is small, extraction is normally performed before analysis. In this article, using the merits of Fourier transform infrared spectrophotometer (FTIR) and energy dispersive X-ray fluorescence spectrometer (EDX), we identified discoloration materials and coloring compounds by direct sample measurement without pretreatment. Focusing on an analysis of color, this article describes some example analyses that explore causes of discoloration and coloration from organic and inorganic compounds, using an analytical approach that combines FTIR and EDX.
