Procedure (See Chromatography, Appendix IIA.) Use a gas chromatograph capable of split and splitless capillary column injection and equipped with a flame ionization detector and a 25-m x 0.53-mm (id) fused-silica capillary column coated with a 2.0-p.m film of 5% phenyl/95% methylsilicone liquid phase, or equivalent, and a 30-m x 0.32-mm (id) fused-silica capillary column, or equivalent, coated with 1.8-p.m film of (6% cyanopropylphenyl) methylpolysiloxane liquid phase, or equivalent, connected in series, with the first column that was described placed behind the second. Set the injector temperature to 150°, the detector to 250°, and the oven to 40° isothermal. Use helium as the carrier gas at a flow rate of 4.4 mL/min. Set the split flow at a rate of 98 mL/min.
