    • In an embodiment, a method for manufacturing a chromatography apparatus such as a thin layer chromatography (“TLC”) plate is disclosed. The method includes forming a layer of elongated nanostructures (e.g., carbon nanotubes), oxidizing the elongated nanostructures to form a surface enriched in oxygen moieties, and at least partially coating the oxidized elongated nanostructures with a coating. The coating includes a stationary phase and/or precursor of a stationary phase for use in chromatography. The stationary phase may be functionalized with hydroxyl groups by exposure to a base or acid. The stationary phase may further be treated with a silane (e.g., an amino silane) to improve the performance of the chromatography apparatus. Embodiments for TLC plates and related methods are also disclosed.
    • 在一个实施方式中,公开了薄层色谱(“TLC”)板等色谱装置的制造方法。 该方法包括形成细长的纳米结构层(例如,碳纳米管),氧化细长的纳米结构以形成富含氧部分的表面,并且用涂层至少部分地涂覆氧化的细长纳米结构。 涂层包括用于色谱法的固定相和/或固定相的前体。 固定相可以通过暴露于碱或酸而被羟基官能化。 进一步用硅烷(例如氨基硅烷)处理固定相以改进色谱装置的性能。 还公开了TLC板的实施例和相关方法。
