【摘要】 脉冲微反-色谱法是气相色谱技术在催化材料评价和筛选、催化反应机理和动力学研究中的成功应用,但由于结构设计和技术基础以及学科的交叉性等方面的原因,目前普遍存在稳定性和重复性不好的问题。因此,本文系统研究了目前脉冲微反-色谱的现状、存在的问题及其原因,探讨改进和提升脉冲微反-色谱技术性能的可能性,为提高这一技术的应用水平提供了有用的参考信息。更多还原

【Abstract】 The pulse micro-chromatography is the successfull application of gas chromatography technology in catalyzing material appraising and screening,and the research of catalytic reaction mechanism and dynamics.But as the result of structural design and technology base,as well as the discipline overlapping,the present pulse mi- cro-chromatography system universally has the problem of bad stability and repeatability.Therefore,systemic stud- ies have been carried out on the present situation,and the existence question and reasons of the pulse micro-chro- matograph system,for the possibility to improve and promote the technical performance of the pulse micro-chroma- tograph,and to enhance the application level of this technical,providing more useful reference information.更多还原
