Linear Combination of "Colors": An Igor Activity
- 1) Collect the UV-Vis spectra for red, yellow, and blue food coloring solutions.
- 2) Download ".csv" file (ASCII format) to a USB drive and return to your computer.
- 3) "Load" these three sets of data (6 waves in total) into Igor and plot all three data sets on a single graph (360 nm - 800 nm).
- 4) Now, collect the UV-Vis spectrum of a mixture provided; download, load into Igor, and plot of separate graph.
- We would now like to analyze this UV-Vis data of the mixture to determine the amount of each of the dyes present. What we are doing is "simulating" the mixture spectrum.
- 5) "Duplicate" the mixture wave associated with the absorbance and call this wave "sim" for simulation.
- 6) Go to the "command line" (box at the bottom of all Igor Experiments)...and type in sim=0.333*red_abs+0.333*yellow_abs+0.333*blue_abs, enter <--this command defines the wave "sim."
- 7) Now append the sim trace/wave to the graph with your mixture spectrum...if the mixture spectrum was 1/3 red, 1/3 yellow, 1/3 blue, then it should match pretty well, but it probably is not 1/3, 1/3, 1/3...
- 8) in the command window, click on the sim=... statement, it will highlight, then hit enter to move this to the command line...edit the 1/3 coefficients to make the sim match your mixture spectrum...done.
