有机皂土弹性石英毛细管色谱柱的制备及其应用研究
Preparation and application of Bentone-34 fused-silica capillary column
【摘要】 在沉积氯化钠纳米晶体的20m×0.25mm弹性石英毛细管柱上,采用动态法涂渍了50%Bentone—34、50%邻苯二甲酸二壬酯混合固定液,并对该色谱柱的色谱分离性能进行了评价。结果表明用此方法制得的弹性石英毛细管柱对C8芳烃和二甲基萘有较强的分离能力,特别适用于2,6-二甲基萘纯度的测定。
【Abstract】 50%Bentone-34(organic soap) and 50%dinonyl(0-) phthalate(DNP) mixed stationary phase was coated on a fused-silica capillary column(20m×0.35mm) deposited with sodium chlonide nano-crystalline. The separation property of the column was evaluated.The results indicate that the capillary column has strong separation power for C8 aromatics and dimethylnaphthalene compounds,especially suitable for the analysis of the purity of 2,6-dime thylnaphthalene.
