集束毛细管柱用于工业化学品的快速气相色谱分离

集束毛细管气相色谱柱是一种新的气相色谱柱型考察了用集束毛细管柱（涂渍ＳＥ３０和Ｃａｒｂｏｗａｘ２０Ｍ）进行工业化学品快速气相色谱分离，并对其色谱性能作了评价，色括流速、柱温对柱效的影响，柱容量的考察和重现性实验典型火炸药成分ＤＮＴ、ＴＮＴ在ＳＥ３０集束毛细管柱上能快速分离重要工业化学品（二甲苯，二甲酚）在Ｃａｒｂｏｗａｘ２０Ｍ集束毛细管柱上有较好的分离实验结果表明集束毛细管气相色谱柱具有的特性是分析快速，柱容量较大，重现性好，对重要工业化学品成分可进行快速有效的分离

Application of Multicapillary Column to High Speed GC Separation of Industrial Chemicals

Two multicapillary coluumns(SE 30 and Carbowax 20M)were used for high speed GC separation of positional isomers of industrial chemicals The performances of the two multicapillary columns were also evaluated,such as the effects of carrier velocity,column temperature and sample capacity Two typical explosive isomers(DNT and TNT)were well separated on SE 30 multicapillary column,while some important chemicals(e g xylenes,xylenols)were separated on Carbowax 20M multicapillary column at high speed The multimulticapillary column shows the feature of fast analysis,relatively lower column temperature and larger sample capacity
