GC Analysis of Aromatics in Reformulated Gasoline on SUPELCOWAX® 10

GC Analysis of Aromatics in Reforµlated Gasoline on SUPELCOWAX® 10

Conditions

column SUPELCOWAX 10, 60 m x 0.25 mm I.D., 0.25 µm (24081)
oven 50 C (3 min), 15 C/min to 265 C (5 min)
carrier gas helium, 30 cm/sec
sample reforµlated unleaded gasoline
injection 0.5 µL, 200:1 split
liner 4 mm I.D., splitless type, single taper wool packed FocusLiner(TM) design
inj. temp. 250 C
detector FID, 265 C

Description

Analysis Note This application illustrates the analysis of a sample of reforµlated gasoline on the SUPELCOWAX 10 column. Due to the polar nature of the phase, the aliphatics elute earlier than the aromatics. There is some overlap in the elution ranges, however it is not as severe as that exhibited by a nonpolar column.
