[Determination of C1-C5 composition of liquefied petroleum gas by capillary gas chromatography].
In this paper, thirteen C1-C5 hydrocarbons in liquefied petroleum gas were separated and determined by using capillary gas chromatography. The cloumn used was 50 m x 0.53 mm i.d. HP PLOT-Al2O3. A standard mixture of known composition was used for the determination of correction factots and the corrected area mormalization was used for quantification. The relative standard deviations (n = 5) were 0.39%-5.4%. Ethane, ethylene and butene were separated to baseline.
