TANDEM DIFFERENTIAL MOBILITY ION MOBILITY SPECTROMETER FOR CHEMICAL VAPOR DETECTION |
摘要 |
A DMS-IMS chemical sensing system employs two ion-separation technologies in tandem to extract signals of specific chemicals from the glut of signals present. The sensing system generally includes an atmospheric pressure ion generation system, a Differential Mobility (DMS) system, a time-of-flight IMS (TOF-IMS) system, and an ion detector system. The DMS extracts a narrow range of trace chemicals from an environmental sample for subsequent analysis, and a TOF-IMS then analyzes the resulting narrow range of isolated chemicals, allowing compound-specific detection thresholds at sub-ppb concentrations. |
