The chromatography column was 25 m long, 0.53 mm I.D., and carried a 5 mm film of methyl phenyl silicone stationary phase It was operated at a flow rate of 4 ml/min, split 2:1 in a split/splitless injector. The separation monitored by a flame ionization detector is shown in figure 48. The column oven was initially held at 45C for 3 min., and then programmed up to 280C at 4/min. 10% of the eluent passed to the detector and the remainder to the light pipe.. for solute identification, providing reference spectra were available.
