    • The present invention relates to a radial disk type ion mobility spectrometer, comprising: an ionizing chamber which is made of a cylindrical tube, and includes an inlet for supplying sample gas therethrough, an ionizing means for ionizing the supplied sample gas to generate ions having a predetermined polarity, and a slit formed by cutting away a part of a cylindrical wall corresponding to a predetermined width for discharging the ions therethrough; a shutter grid installed adjacent to the slit of the ionizing chamber for controlling passage of the ions through the slit; a drift chamber which is a hollow tube having a predetermined thickness and including an outer cylindrical wall having a predetermined diameter and an inner cylindrical wall having an inner diameter equal to an outer diameter to the ionizing chamber so that an annular space is formed between the inner and outer cylindrical walls, of which a part of the inner cylindrical wall corresponding to a width larger than that of the slit is cut away such that the ions passing through the slit can be introduced into the annular space through the cutaway part of the inner cylindrical wall, and of which the inner cylindrical wall is engaged with the cylindrical wall of the ionizing chamber in such a manner that the drift chamber communicates with the ionizing chamber through the slit and the cutaway part of the inner cylindrical wall; and a collector installed onto an inner surface of the outer cylindrical wall of the drift chamber for collecting the ions that have passed through the drift chamber.
    • 径向盘型离子迁移谱仪本发明涉及一种径向盘式离子迁移谱仪,包括:一个由圆柱形管制成的电离室,包括一个用于提供样品气体的入口,用于使所提供的样品气体离子化的离子化装置, 通过切除与预定宽度对应的圆筒壁的一部分而形成的狭缝,以将离子排出; 安装在电离室狭缝附近的挡板,用于控制离子通过狭缝的通道; 漂移室,其是具有预定厚度的中空管,并且包括具有预定直径的外圆柱形壁和内径等于离子化室的外径的内圆柱形壁,使得在内部 并且外圆柱形壁,其中对应于宽度大于狭缝的宽度的内圆柱形壁的一部分被切掉,使得通过狭缝的离子可以通过内圆柱体的切口部分被引入环形空间 所述内圆柱壁与所述电离室的圆筒壁接合,使得所述漂移室通过所述狭缝和所述内圆筒壁的切除部分与所述电离室连通; 以及安装在漂移室的外圆筒壁的内表面上的收集器,用于收集已经通过漂移室的离子。
