The "GED-ICP-MS real-time trace metal monitoring system" integrates a Gas Exchange Device with Inductively Coupled Plasma Mass Spectrometry to deliver continuous five-minute monitoring of ten trace metals in airborne particulate matter, with detection limits down to 0.05 ng/m³. Field-validated in an urban environment, the system overcomes both the temporal lag of filter sampling and the sensitivity limit of XRF, offering a next-generation solution for urban air quality management.

The technology transforms GED-ICP-MS from an analytical instrument into a dynamic health-risk assessment platform, integrating five-minute temporal resolution with chemical resolution across ten trace metals. The resulting dual-resolution architecture is the first internationally reported system capable of simultaneously capturing physical and chemical drivers of particulate health risk, and the underlying research was awarded the Journal of Hazardous Materials Best Paper Award 2025.

Aligned with 2050 net-zero policies, the technology addresses three pressing needs: non-exhaust emission management in the electric-vehicle era, real-time environmental enforcement, and exposure early warning for sensitive populations. It can be deployed in mobile monitoring vehicles, roadside stations in traffic hotspots, and alert systems near schools and hospitals, providing scientific evidence for regulatory enforcement and policy verification.
