迎头色谱法在评价调湿剂性能上的应用

利用迎头色谱脱附曲线，测定了水蒸汽在调湿剂中的扩散系数。结果表明，当清除了载气流速、调湿剂粒径以及色谱柱轴向扩散等众多干扰因素的影响后，由迎头色谱法测得的水蒸汽在调湿剂中的扩散系数值可用于评价调湿剂的响应速度。

The application of frontal chromatography to comment on the property of humidity-controlling agent

In this paper, the diffusion of water vapour in humidity - controlling agent has been determined by frontal chromatography. The result shows that the obtained diffusion can be used to comment on the property of humidity - controlling agent when several influential factors, such as the flow rate of carrier gas, the particle size of humidity - controlling agent and axial diffusion, has been e1iminated. This paper will provide theoretical basis for further studing the relation between the structure and characteristic of humidity - controlling agent.
