Compact Electrochemical Sensor Cells (280)
Problem: Need compact, adaptable electrochemical cell design for use in practical, portable sensors
Project Activity Scope (from Technical Overview Chart): Sensors and Devices through Integrated Systems
PNNL Solution:
- Design cell with small dead-volume and variable flow volumes that allows sample size to be varied over wide ranges
- Incorporate high surface area, chemically specific sorbent material into working electrode
- Sorbent can be tailored for different target analytes
Capabilities Employed to Meet Client Needs: Component design; adaptation of commercial components (when available) to meet system requirements; material selection for compatibility with sensor requirements and fabrication processes; microfabrication with laser machining; subsystem assembly and evaluation; system integration and testing.
