erratum at 12(3) p 200 calculation errors associated with Figure 2:

First, the width of the 10-min peak should have been 8.0 mm, not 0.8 mm. Second, I inverted the millimeter-to-minute conversion factor in my calculation, so the true retention time for the 10-min peak should be ~38.5 min, not 84 min.
