Imaging ftir spectroscopy
WitrynaIn this research, the absorption values of each FTIR spectrum acquired in the range of 4000–400 cm −1 were utilized to perform the PCA. Table 5 exhibits variance that … WitrynaIn conjunction with the IR spectroscopy, we use attenuated total reflection (ATR) to directly examine materials-solid or liquid-with minimal sample preparation. The Cary 620 FTIR Microscope allows us to do imaging and mapping to identify chemical information and study very specific areas and map functional groups.
