Chemical analysis using hyphenated low and high field ion mobility

摘要

Using combined orthogonal techniques, such as low (IMS) and high (FAIMS) field mobility techniques, offers several advantages to ion detection and analysis techniques including low cost, no vacuum required, and the generation of 2-D spectra for enhanced detection and identification. Two analytical devices may be operated in different modes, which results in overall flexibility by adapting the hyphenated instrument to the application's requirements. With the IMS-FAIMS hardware level flexibility, the instruments may be configured and optimized to exploit different trade-offs suitable for a variety of detection scenarios of for different lists of target compounds.
