弹性石英毛细管柱因其柔性而大大方便了使用;其惰性又改善了色谱性能,所以它在高效色谱领域的作用与日俱增,这就有必要大力推广普及这一优良柱型。研制简易的拉伸设备是为此所作努力的一个方面。我们曾报道过以氢氧焰作熔炉拉伸弹性石英毛细管的初步结果。该法的优点是设备简单、成本较低、缺点是火焰的稳定性对毛细 Flexible quartz capillary column because of its flexibility and greatly facilitated the use of its inert and improved chromatographic performance, so its role in the field of high efficiency chromatography is increasing, it is necessary to vigorously promote the popularity of this excellent column. Developing a simple stretching device is one aspect of this effort. We have previously reported the initial results of a flexible quartz capillary stretched with hydrogen and oxygen flames. The advantage of this method is simple equipment, low cost, the disadvantage is the stability of the flame on the capillary
