%X A capillary column HP-AlO2O3/S PLOT(50 m x 0.32 mm i.d. x 8 microm) has been used for the analysis of trace hydrocarbon impurities in high purity isobutene. The results showed that these hydrocarbon impurities could be well separated and with the liquid-phase sample injection valve the disproportionation of sample composition could be avoided. The results also show high accuracy and precision.
