For peak response, ZChrom chromatography manager software version 4.2.was used to calculate the statistical data of different parameters like, retention time (tR), peak area (A) symmetry factor of SFV and theoretical plates (N) (Table 1).
The robustness of the method were determined by minor deliberate changes in different experimental parameters and studied their effects on retention time, peaks resolution, peak area and height.
The N1s spectrum of PI presented two components, the main one at 400.1 eV, related to C-N imide bonds, and one at lower binding energy (398.8 eV), which can be assigned to NH2 group present in the end of PI chain and represents around 4% of the total peak area. In the O1s core level region, components at 531.5, 532.8, and 537.3 eV binding energy were detected.
The walk through the White Peak area is eight to ten miles on varied terrain and will take approximately five hours.
For both the TargetLynx and Skyline-daily software environments, concentrations were calculated using the peak area response and a 5-point calibration curve with 1/x weighting.
Using the characteristic peak area data produced by the UPLC analyses, PCA was conducted to distinguish between the saffron samples according to their treatment (irradiated versus nonirradiated).
By fitting, it can be concluded that the binding energy of the peak position and curve peak area of Fe element in corrosion solution of steel bar in chloride salt solution are shown in Table 2, the relative content of FeO is 32.3%, and the relative content of FeOOH is 67.7%.
