Complete capillary electrophoresis process on a drone: towards a flying micro-lab.

Area of Science:

• Analytical Chemistry
• Robotics
• Environmental Science

Background:

• Remote and hazardous locations pose significant risks for on-site scientific investigation.
• The need for in situ (on-site) analytical instrumentation across various scientific fields is critical.

Purpose of the Study:

• To design a fully automated, drone-mountable chemical analysis system for remote environmental monitoring.
• To enable autonomous, in situ analysis of volatile and non-volatile chemicals in the air.

Main Methods:

• Development of a lightweight (<800g) autonomous chemical analysis system with drone-mounting capability.
• Utilized capillary zone electrophoresis for automated separation of collected analytes.
• Employed a miniaturized contactless conductivity detector for quantification down to sub-micromolar levels.

Main Results:

• Demonstrated successful sampling and separation of volatile amines, organic acids, inorganic cations, and proteins in aerosol form.
• Confirmed the feasibility of performing capillary electrophoretic analysis on a hovering drone.
• Wireless data transmission capability was integrated into the system.

Conclusions:

• The developed autonomous drone-based analytical system enables remote investigation of hazardous environments.
• This technology serves as a foundation for more advanced autonomous complex sample analysis.
• Minimizes human exposure risks in dangerous or inaccessible locations.
