Fourier transform infrared (FT-IR) spectroscopy, Raman spectroscopy and thermal analysis are three valuable analytical tools for research and quality-control applications. Each method has its own strengths and weaknesses that make it ideal for some applications and not the best choice for others.
In general, Raman and FT-IR both look at the molecular structure of a material and thus are best suited for fingerprinting specific materials. Raman spectroscopy is the typically the fastest because it usually requires the least sample preparation time, while FT-IR is less expensive and offers a wider range of sampling accessories. Thermal analysis tends to be ...
