Set up your spectrometer to collect a full absorbance spectrum with a computer and Logger Pro<\/i> 3. Follow these steps to prepare the column of % transmittance data:
\n1) Open the Data menu and choose New Calculated Column.
\n2) (Optional) Name the new column % transmittance, and use %T as the short name.
\n3) In the Equation box, type in: 100\/10^(Absorbance)
\n[Note: to accurately enter “Absorbance” in the equation field, simply click the Variables (Columns) button and choose Absorbance. Close the parentheses.]
\n5) Click Done.<\/p>\n
Next, set up your graph to plot both absorbance and % transmittance on the same graph. Follow these steps:
\n1) Place the cursor anywhere on the graph itself and double click. A new dialog box will appear.
\n2) Click the Axes Options tab.
\n3) Check the box next to “Right Y-axis”.
\n4) Check the box next to the column of % transmittance data.
\n5) Click Done.<\/p>\n
Your graph will be scaled so that the absorbance data uses the left-hand Y-axis and the %T data uses the right-hand Y-axis. In addition, the plots are color coded. <\/p>","protected":false},"excerpt":{"rendered":"
