Figure 10.5 (a) Gas chromatogram obtained from a natural cis-3-hexen-1-ol fraction after
unidimensional separation: CPWax-52-CB column 25 m, 0.32 mm i.d., 1.2 m film thick-
ness; carrier gas He, 0.7 bar; oven temperature, 60 °C (5 min)–180 °C at 2 °C/min). (b) Gas
chromatogram obtained from a natural cis-3-hexen-1-ol fraction after multidimensional sepa-
ration: SPB-5 pre-column, 30 m 0.25 mm i.d., 1 m film thickness; carrier gas He, 1.8 bar;
oven temperature; 60 °C (5 min)–100 °C at 2 °C/min with a hold of 5 min and then pro-
grammed to 220 °C at 5 °C/min; DB-Wax column 30 m 0.25 mm i.d., 0.25 m film thick-
ness; carrier gas He, 1.3 bar; oven temperature 60 °C (5 min), then rising to 220 °C at
2 °C/min (cf. Table 10.3). Reprinted from Journal of High Resolution Chromatography, 15,S.
