采用乙醇化学气相沉积法制备了碳纳米管分子自组装气相色谱固定相。一个主要优点是乙醇被发现是一种优良的碳源，可以产生高纯度的多壁碳纳米管，其中非管状碳杂质非常少。纳米管不是垂直排列的，而是以随机分布的结构平放在圆柱表面上。CNT相能够分离具有不同极性和挥发性的各种有机化合物，其中每米的板数范围从900到1280。色谱行为经典，精密度好。
The synthesis of the gas chromatography stationary phase by molecular self-assembly of carbon nanotubes (CNTs) via a novel ethanol chemical vapor deposition process is presented. A major advantage is that ethanol was found to be an excellent carbon source that generated highly pure multiwalled carbon nanotubes with very little non-tubular carbon impurities. The nanotubes were not vertically aligned but lay flat out on the column surface in a randomly distributed configuration. The CNT phase was able to separate a wide range of organic compounds with diverse polarity and volatility, where the number of plates per meter ranged from 900 to 1280. It also showed classical chromatographic behavior and good precision.
