Unformatted text preview: have different retention times due to different amounts of time spent with the stationary phase. Separation on the chromatograph can then be seen. Discussion/ Conclusion: Compounds in the unknown are: n-Pentane, n-Hexane, Benzene, n-Heptane, n-Octane, o-Xylene, 2-Methylpentane, Toluene, and p-Xylene. Both the precision and accuracy of the experiment can be improved if more exotic, larger columns were used. However, the retention times of standard components in the standard run do match up quite precisely with those in the unknown run....
