The given retention time for the ethyl acetate is 3.62 and isopropanol is 4.01. The retention time for ethyl acetate and isopropanol in standard 1 is 3.72 and 4.14. The retention time for ethyl acetate and isopropanol in standard 2 is 3.72 and 4.10. Finally, the retention time for ethyl acetate and isopropanol in standard 3 is 3.70 and 4.13. By making the calibration curve, the concentration was figured out by placing y1 as the peak area and solving for x, which is the concentration.
