                           Figure 4.12 (continued) (c) An expansion of the inset region from (b), with the normal
                           alkanes shown as (a–e). Other unidentified components (f–i) are presented to locate specific
                           peaks for comparison purposes. (d) A light gas oil analysed under the same conditions as for
                           the cycle oil, showing the same expanded region. In this case, the oil has not been treated in
                           the same manner as the cycle oil, so it retains the components that were absent from the cycle
                           oil. Peaks (a–i) are the same as those seen in (c).
