Analysis of Hydrocarbon Impurities in High Purity Isobutene by Gas Chromatography
气相色谱法分析高纯异丁烯中的微量烃类杂质

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.
