用扫频方波发生器同时打开和关闭双门离子迁移谱仪的进、出口门，产生迁移率干涉图。傅立叶变换的干涉图恢复正常的迁移率谱。建立了该方法的理论，并得到了正背景反应物离子和1-甲基萘在N_2漂移气体中的转换谱。气相色谱迁移率检测方法的潜在优点包括快速收集完整的迁移率谱和提高检测器灵敏度。新方法应普遍适用于其他时间分散技术，如飞行时间质谱。
A mobility Interferogram is generated when the entrance and exit gates of a two-gate ion mobilityspectrometer are si-multaneously opened and closed by a frequency sweeping square wave generator. Fourier transformation of the Inter-ferogram recovers the normal mobility spectrum. A theory for the method is developed, and transformed spectra are obtained for the positive background reactant Ions and for1-methylnaphthalene In N2 drift gas. Potential benefitsof the method for mobility detection In gas chromatography Include rapid collection of complete mobility spectra and increased detector sensitivity. The new method should be generally applicable to other time dispersive techniques such as time of flight mass spectrometry.
