FTIR Spectograph FTIR Spectral Interpretation We have shown that FTIR spectroscopy is a very powerful tool with many applications, however data interpretation is not straightforward. By nature, the total spectrum generated is a series function of absorbed energy response (hence the Fourier Transform po...
It uses this information to create a spectrum, which is essentially a graph showing the different frequencies of infrared light absorbed by the sample. Data Interpretation: By analyzing the absorption pattern (spectrum), scientists can determine what types of bonds are present in the sample. This ...
The method lies in the interpretation of the pixel distribution in Ts-NDVI space. If an image contains a large space of soil water content and green vegetation, the space presents a triangle. The triangle formed because the surface temperature decreases as vegetation cover increases. Scatter plot...
In order to have statistical analysis, all experiments were conducted with at least triplicates of samples (n = 3), where the values were averaged and standard deviation (SD) was used as error on graph plots. Although, in all swelling assays 5 samples of each group (n = 5) were used ...
In other words, the calibration curve is obtained by replacing the measured instrumental signal used in univariate calibration (e.g., absorbance at a single wavelength) with the NAS (r*) allowing a simpler interpretation of the response signal [53]. Accuracy (RMSE) This parameter indicates the...
