1 / 1 Summary u00e2u20acu0153mu00e3u2030todo for gas chromatography for the detecu00e3u2021u00e3u0192o a marker compound in a hydrocarbon petru00e3 "Leo or a combustu00e3ufffdvel lu00e3ufffdquidou00e2u20acufffd mu00e3todo for gas chromatography for detecu00e3u00a7u00e3u00a3o of a compound in a first marker and a second marker. A combustu00e3u00advel in two channels: (a) a first capillary column coated with a stage and a second estacionu00e3ria with polisiloxanoThe capillary column coated with polyethylene glycol; and (II) a third capillary column coated with polimetilfenilsiloxano capillary column and a fourth operation.The steps su00e3u00a3o: (a) introducing a sample of combustu00e3u00advel inside of a first column to produce a first effluent; (b) to introduce only a poru00e3u00a7u00e3u00a3o first effluent in a second column to produce a second effluent; (c) to allow the second effluent passes through a At a espectru00e3u00b4metro mass; (d) to introduce a second sample in the third column to produce aCash effluent; (E) to introduce only a poru00e3u00a7u00e3u00a3o third effluent in the fourth column to produce a fourth effluent; (f) to allow the room effluent pass atravu00e3s a espectru00e3u00b4metro mass.
