The percent water in methyl alcohol can be determined by gas chromatography using
a capillary column coated with a non-polar stationary phase and a thermal
conductivity detector. A series of calibration standards yielded the following results:
Water content (% w/w) Peak height (arbitrary units)
0.00 1.15
0.0145 2.74
0.0472 6.33
0.0951 11.58
0.1757 20.43
0.2901 32.97

    Why are chromatographic peaks broader than would be expected solely on
    the basis of the random nature of solute migration through a chromatographic
    column?
