Bild Closed gas loop, high-resolution IMS with gas chromatographic pre-separation for breath gas analysis

In many breath gas analysis applications, real-time and bed-site analysis is required to achieve true applicability for clinical diagnosis. Thus, we built a compact, closed gas loop, high-resolution GC-IMS. The ion mobility spectrometer achieves a mobility resolution of R=90. The GC-IMS is equipped with a filter re-circulation system providing a continuous supply of dry and clean drift gas, so that no external supply is needed. Hence, the entire system fits in a 19″ housing (6 RU height).
