Figure 4.12 (a) Surface response plot of a light cycle oil analysed by GC GC. The col-
umn set was a BPX5–BPX50 combination, with the second column being 0.8 m in length. A
6 s modulation time was used, in conjunction with a 1°C/min temperature programme rate.
The cycle oil has been reformed to remove the cyclic alkanes. (b) The same data as in (a), but
presented as a contour plot in this case.
