The injector temperature was maintained at 270 the volume of injected sample was02 KAL; pressure 854kPa, total flow 76.8 ml/min, column flow 1.21 mLlmin, linear velocity 40.5 cm/s, purge flow 3.0 mL/min, ratio: ion source term perature 230 C; scan mass range of 40-600; and interfac temperature 2 c The identification of compounds was per- formed by comparing their mass spectra with data from NISTO5(National Institute ofstandards and Technology, US), WILEY 8.and
