Generality of the scattering dilution method for FT-IR spectrometry

The scattering dilution method (SDM) was proposed as one measurement method of powders for FT-IR spectrometry. It was confirmed that SDM was a general measuring method for powders with a higher or lower refractive index for all cases. In the case of obtaining the IR spectra of powders, although we might not need to use SDM for transparent or non-colored samples, it is worthy to first utilize SDM for colored samples or mixture samples.
