WebJul 5, 2024 · The relationship between linear deviation with the Beer-Lambert law and spectral resolution was verified by measuring SO 2 at total column concentrations of 4.3 mg/m 2 to 1285.7 mg/m 2 with 6 spectrometers with different spectral resolutions. It was found that the higher the spectral resolution was, the smaller the linear deviation would be. WebSep 27, 2024 · Beer’s Law Example Calculation: A sample having a maximum absorbance value of 275nm. It has a molar absorptivity of 8400M-1cm-1. 1cm is the width of a cuvette. A spectrophotometer value detected A=0.70. calculate the concentration of the sample. By using Beer’s law, we will calculate the concentration of the sample. A= εbc.
