From laboratory to full scene coverage, Duktech's carbon source and sink monitoring solution has sparked industry discussions

The 18th China International Forum and Exhibition on the Application and Development of Online Analytical Instruments was successfully concluded at the Hangzhou International Expo Center from November 12th to 14th, 2025. Beijing Duktech Technology Co., Ltd. showcased its core technological achievements at the exhibition, and the company's product manager, Fu, delivered a special report titled "Carbon Source and Carbon Sink Stereoscopic Monitoring Scheme Based on Photoacoustic Spectroscopy Technology" on site. With its independent innovation technology system and full scenario application value, it has won widespread attention and high recognition from industry colleagues.

This exhibition is jointly organized by the Online Analytical Instrument Branch of the China Instrument and Meter Industry Association and the Analytical Instrument Branch of the China Instrument and Meter Society. With the core orientation of "efficiency/quality/energy saving/safety/environmental protection", it brings together enterprises, research institutes, and industry experts in the field of online analytical instruments, focusing on core issues such as instrument technology innovation and green application upgrading. It is a platform for industry technology exchange and market docking. As an innovative enterprise deeply engaged in the field of trace gas analysis, Duktek has fully demonstrated its technological accumulation and product strength in the field of carbon source and sink monitoring.

In the report, Manager Fu provided a detailed explanation of Duke Tech's core innovation based on photoacoustic spectroscopy technology - targeting the precise and three-dimensional needs of greenhouse gas monitoring under the "dual carbon" target. The solution is centered around the independently developed DKG-ONE series photoacoustic spectroscopy multi gas analyzer, integrating multiple modes such as flux monitoring, drone monitoring, emergency monitoring, and navigation monitoring. It can achieve trace detection of more than 1000 gases such as CO ₂, CH ₄, N ₂ O, with a detection limit as low as 0.1ppb, a sample gas requirement of only 15ml/time, and an analysis time shortened to 3-10 seconds, which is 1000 times more accurate than traditional methods. The solution supports three-dimensional monitoring of sea, land, and air, and can be widely applied in multiple scenarios such as automatic monitoring of ambient air, greenhouse gas flux detection, and pollution tracing of landfills. It provides full cycle data support for carbon source and sink accounting and emission reduction effect evaluation, effectively solving industry pain points such as high cost, poor real-time performance, and limited coverage of traditional monitoring.

During the exhibition, the Duke Tech booth attracted many exhibitors to stop and inquire. The physical products displayed on site, such as portable photoacoustic spectroscopy gas analyzers and unmanned aerial vehicle onboard monitoring systems, received praise for their compact size, precise performance, and flexible application modes. Experts and scholars from Shanghai Environmental Monitoring Center, Sinopec and other units had in-depth exchanges and reached multiple preliminary consensuses on issues such as technical cooperation and scenario implementation. At the same time, Duktek also deeply participated in various technical forums of the exhibition, fully understanding the development trends and market demands of the online analytical instrument industry.

This exhibition not only demonstrates Duktech's independent innovation strength in the field of photoacoustic spectroscopy monitoring technology, but also broadens the channels for industry cooperation. In the future, Duktech will continue to focus on the "dual carbon" strategic needs, deepen the research and application expansion of photoacoustic spectroscopy technology, launch more high-performance and low-cost domestically produced monitoring equipment, provide more reliable technical solutions for precise management of carbon sources and sinks, and ecological environment governance, and help achieve the goal of green and low-carbon development.
