IMS Optimization for New Applications (234)
Problem: While broadly applicable with major advantages, IMS sensor designs may need to be tailored for new uses
Project Activity Scope (from Technical Overview Chart): Mechanisms through Integrated Systems
PNNL Staff Solution:
- Applications requiring IMS adaptation include:
- analysis of a different sample phases (e.g., liquids, etc),
- complex sample matrices,
- analytes with low proton or low electron affinity.
- Success in these cases may require:
- a tailored sample introduction unit,
- a different ionization source for the target analyte, or
- addition of a preselective sampling inlet (e.g. membranes, fast chromatography) and manipulating the gas phase chemistry in the drift tube to detect analytes in a complex background.
Capabilities Employed to Meet Client Needs: Ion mobility spectrometry; gas phase ion chemistry; ionization source design; data acquisition software development; sampling methodologies; data analysis algorithms; analog and digital electronics, including high voltage implementation; mechanical component and packaging design; system integration; field testing and demonstration; field deployment and customer user training; develop operations and service manuals.
