Why does QTA use Fourier Transform?
The QTA system is comprised of FT-NIR or Mid-IR due to its resolution flexibility and its wavelength accuracy in comparison to other types of NIR systems. Lower resolution settings generate a high signal-to-noise ratio spectrum that is good in low concentration analysis. Higher resolution settings enable QTA to expand capabilities into specialty trait analysis. The single resolution feature for other types of NIR systems shows less flexibility than FT-NIR.
