If the plot is not linear, either your absorbance values are incorrect or your spreadsheet plot is set up incorrectly. In this plot, which is called a "Beer's Law plot" (equation 2 on page 2 of this experiment), be sure to enter the concentration values in Molarity instead of the micro-Molar values listed on the cuvettes in the lab window (you need to move the decimal six places to the left). 3Klik Coba gratis selama 1 bulan di sebelah kanan situs web.
