Fourier-transform infrared spectroscopy (FTIR) is a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid, or gas. It measures the interaction of infrared light with matter using the concepts of FTIR spectroscopy. GemmoFTIR is an extremely useful instrument for gemologists, offering significant information regarding the chemical makeup and authenticity of Jewellery.
