  • About Company

    EIPROTECH is an innovation-driven scientific instrument company dedicated to molecular-level environmental diagnostics. Founded in 2019 by Dr. Yaping Zhang, the company focuses on the development of in-situ, automated, and intelligent analytical technologies for aerosol and trace organic pollutants.

    Building on long-term expertise in aerosol science, environmental monitoring, instrument engineering, and field applications, EIPROTECH has developed the Automated Collection and Thermal desorption System (ACTS), a modular platform that enables automated particle collection, thermal desorption, soft-connection injection, and GC-MS analysis. The system is designed to bring laboratory-grade organic molecular analysis into real-world monitoring environments.


    EIPROTECH’s technologies support high-time-resolution and molecularly resolved analysis of organic aerosols and related pollutants, providing valuable information for air quality research, source apportionment, industrial emission diagnosis, environmental regulation, and health-related exposure assessment.

    Through instrument development, method innovation, demonstration applications, and collaborative research, EIPROTECH aims to provide reliable, deployable, and cost-effective solutions for advanced environmental monitoring. The company is committed to helping researchers, regulators, and industrial partners better understand complex pollution processes at the molecular level and translate scientific measurements into actionable environmental insights.
