【摘要】 <正> 在色谱分离技术领域中,毛细管气相色谱由于它的高效和快速占有十分重要的地位,并已得到广泛应用。 1959年Desty等发明了螺旋形玻璃毛细管柱,它具有制做简便、涂渍容易、表面特性较好等优点,(但因其为刚性而具有性脆易碎的缺点),1979年Dandenau等报道了弹性石英毛细管柱。它实质上是利用拉制更多还原

【Abstract】 A flexible glass capillary column has been developed. An apparatus for drawing this column was homemade. The fresh-drawn glass capillary was coated externally with polyimide. It is strenthened and flexible similar to a fused silica column but using less expensive material and simpler drawing apparatus. The internal coating layer can be produced by using some procedures which are similar to those of rigid glass capillary, A column, of which internal surface is roughed with Silanox, is evaluated generally.更多还原
