Sept 3 UV Vis-FTIR-DSC
Objective
My group was assigned to use the UV-Vis today, and to use the FTIR, DSC, PXRD on Friday. Note: On Friday Groups A and B will perform the tasks Groups C and D perform on Wednesday and vice versa. DescriptionTasks
DataFigure 1. Shows the weights of the pans, lids and films used for DSC Figure 2. Shows the calibration curve for wavelength 423nm. Beer's Law explains that A= Ɛbc, where Ɛ = molar absorptivity in the units of cm-1*M-1, b = path length, and c = concentration. The molar absorptivity of the malachite green at 617nm is 0.1193. This is identified by translating Beer's Law to the slope of the calibration curve y=mx+b; where y = absorbance (y axis), x = concentration (x axis), and m = molar absorptivity. The standard curve for wavelength 423 has an line fit that is below acceptable values for calibration plots. This is due to the calibration point 1.1.
