A microfluidic chip monitors gases using integrated, motionless pumps

A new microscale gas chromatography system integrates all fluidic components into a single chip for the first time. The design leverages three Knudsen pumps that move gas molecules using heat differentials to eliminate the need for valves, according to a new University of Michigan Engineering study published in Microsystems & Nanoengineering. The monolithic gas sampling and analysis system, or monoGSA system for short, could offer reliable, low-cost monitoring for industrial chemical or pharmaceutical synthesis, natural gas pipelines, or even at-home air quality.
