Trace GC with PTV inlet in splitless mode, 30m DB5 capillary column (J and W Scientific) with 0.25mm i.d. and 0.25 lm film, and was operated at a constant helium flow rate of 1 ml/min. The oven temperature pro gram differed for each lipid class. For hydrocarbons, the starting temperature was 90 �C, rising to 230 �C at 13 �C/min, then to 325 �C at 5.5 �C/min, followed by 13 min at 325 �C. Effluent from the GC entered the GCC III interface, a graphitelined ceramic tube at 1400 �C, where quantitative pyrolysis to graphite, hydrogen gas and carbon monoxide occurred (Bur goyne and Hayes, 1998). The hydrogen gas stream was introduced to the Finnigan Deltaplus XP mass spectrometer via an open split, where a flow of helium carried the H2 gas into the mass spectrometer.
