Globally leading online instrumentation for particulate organic molecular analysis
In-situ, automated molecular analysis for environmental monitoring, industrial applications, and scientific innovation.
About Company
EIPROTECH develops low-cost, innovative solutions for in-situ aerosol collection and thermal desorption GC-MS. Founded in 2019 by Dr. Yaping Zhang, the company is focused on making molecular aerosol analysis more practical, automated, and deployable for environmental
monitoring, scientific research, industrial diagnostics, and health-related applications.Our core platform grew out of five years of engineering to transform a concept into a truly deployable in-situ analytical instrument. We developed a soft-connection front-end design that links the collection and thermal desorption (CTD) unit to a GC using only one
injection needle and a pair of septa, with no GC hardware modification required.This approach reduces system complexity and cost while maintaining strong analytical performance. It also enables rapid switching between in-situ aerosol analysis and regular GC analysis, giving users greater flexibility than conventional hard-plumbed systems.
