Abstract

Mesoporous silica with KIT-6 structure was investigated as a preconcentrating material in chromatographic systems for ammonia and trimethylamine. Its adsorption capacity was compared to that of existing commercial materials, showing its increased adsorption power. In addition, KIT-6 mesoporous silica efficiently adsorbs both gases, while none of the employed commercial adsorbents did. This means that KIT-6 Mesoporous silica may be a good choice for integrated chromatography/gas sensing micro-devices.

摘要

介孔硅 KIT-6 结构作为色谱系统中氨和三甲胺的预浓缩材料进行了研究。其吸附能力与现有商业材料进行了比较，显示出其增加的吸附能力。此外，KIT-6 介孔硅高效吸附这两种气体，而所使用的商业吸附剂均没有。这意味着 KIT-6 介孔硅可能是集成色谱/气体感应微器件的良好选择。
