Beer’s law suggests that a plot of absorbance vs. Virtually all UV spectra are recorded solution-phase 2. Instrumentation – Sample Handling 1. Spectra. It can be seen that the largest relative discrepancy between the spectra occurs at the absorption peaks and the main effect of nonlinearity on the absorption spectra is thus a reduction of the peak height. The third step is to measure the absorbance in the sample with an unknown concentration. Introduction B. 9 2 11 months ago. 0 and 656. Beer’s Law Example Calculation: A sample having a maximum absorbance value of 275nm.
