摘　　要：本文简单介绍了非对称离子迁移谱技术的发展，原理及应用。主要讲述了该技术在产品化过程中遇到的外载气流的不稳给样品峰带来的抖动这一问题，该问题对产品对非对称离子迁移谱技术在产品化过程中的可靠性及稳定性产生的非常重要的影响。本文通过蕈新设计气路连接方式，在气路上另外串接一小型流量控制器，有效的解决了外载气流不稳给气路带来的影响，并通过气路实验对这一结果进行了有效的验证。This article simply introduces the development, theory and application of FAIMS, and deeply describes the problems in the air flow path design during the productization process. These problems cause a serious effect on the performance of the detector based on FAIMS, which means the reliability, stability and other parameters, especially the vibration on the signal peek that came from unstable flow of the pump, the difficulty in the miniaturization of the product. That how these problems affect the performance of detector and how to get rid of these problems is the main issue of the article.
