This paper presents the optimization of a micro gas preconcentrator (μ-GP) system applied to atmospheric pollution monitoring, with the help of a complete modeling of the preconcentration cycle. Two different approaches based on kinetic equations are used to illustrate the behavior of the micro gas preconcentrator for given experimental conditions. The need for high adsorption flow and heating rate and for low desorption flow and detection volume is demonstrated in this paper. Preliminary to this optimization, the preconcentration factor is discussed and a definition is proposed.
本文借助预浓缩循环的完整模型，介绍了一种应用于大气污染监测的微型气体预浓缩器（μ-GP）系统的优化。基于动力学方程的两种不同方法用于说明微型气体预浓缩器在给定实验条件下的行为。本文证明了对高吸附流量、加热速率以及低解吸流量和检测体积的需求。在进行此优化之前，讨论了预浓缩因子并提出了一个定义。
