摘要
采用HP Al2O3/SPLOT(50m×0.32mmi.d.×8μm)毛细管色谱柱对高纯异丁烯中的微量烃类杂质进行了气相色谱方法研究。结果表明,该色谱柱能很好地分离异丁烯中的C1～C4烃类杂质;采用液相进样阀液态直接进样,保证样品不失真,所测定的结果有良好的准确度和精密度。
A capillary column HP-Al_2O_3/S PLOT(50 m×0.32 mm i.d.×8 μm) 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.
