本文介绍了不同吸附剂对气体预富集器性能的影响，目的是在特定的实验条件下，为给定的气体目标找到合适的吸附剂，并选择有效的沉积工艺。本文报道了碳纳米粉、碳纳米管（单壁（SWCNTs）和多壁（MWCNTs））和聚合物（Tenax TA）的表征结果，用于苯预富集装置的开发。根据比表面积大、吸附量大、解吸温度低等条件，为确定苯的预富集吸附剂提供了依据。
This paper presents the evaluation of different adsorbents for the improvement of the performances of a gas preconcentrator by targeting the adsorption of a large range of volatiles organics compounds (VOCs) The objectives of this work are to find the adequate adsorbent for a given gas target in specific experimental conditions and to select an efficient deposition process. Results related to the characterization of carbon nanopowders, carbon nanotubes (single walled (SWCNTs) and multi walled (MWCNTs)) and polymer (Tenax TA) for the development of a device for benzene preconcentration are reported. These results provide guidelines to define the right adsorbent for the preconcentration of benzene according to some specific criterions such as a large specific surface, a high adsorption capacity and low desorption temperature.
