Breaking through the special gas trace detection! The Duktech Laser Photoacoustic Spectroscopy Solution Stunning Wuhan Special Gas Annual Conference

On November 17-19, 2025, the 40th anniversary commemoration conference of the establishment of the National Special Gas Information Station and the 27th annual conference of the National Special Gas were successfully held at the Wuhan Eurasia Exhibition International Hotel. Beijing Duktek Technology Co., Ltd. was invited to participate in a heavyweight exhibition. The product manager of the company delivered a special report titled "Measurement of Trace Impurities in Special Gases Based on Laser Photoacoustic Spectroscopy Technology" on site. With its independently innovated core technology and full scenario solutions, it has won widespread attention and high recognition from industry colleagues.

This annual conference is hosted by Haohua Gas Co., Ltd. and Zhonghao Guangming Chemical Research and Design Institute Co., Ltd., and organized by the National Special Gas Information Station and the editorial department of "Low Temperature and Special Gas". With technology exchange, information release, product display, and business negotiation as the core, it brings together domestic and foreign gas industry, technical experts, scientific research scholars, and enterprise representatives, focusing on key issues such as standard substance application, electronic gas application, and industry technology dynamics. It is an influential industry event in the field of special gases.

As an innovative enterprise deeply involved in the field of trace gas analysis, Duktek's core technological achievements this time hit the pain points of the industry. In the report, the product manager explained in detail the innovative application of laser photoacoustic spectroscopy technology in the detection of trace impurities in special gases. In response to the fact that special gases are the "blood" of industries such as semiconductors and aerospace, their purity directly determines the core requirements of product quality and production safety, this solution relies on laser photoacoustic effect, non resonant photoacoustic cell, cantilever beam optical microphone and other technologies to achieve trace detection of more than 1000 gases such as SO ₂, NH ∝, CH ₄, CO ₂, NO ₓ, VOCs, with detection limits as low as ppb level, and some gases can reach ppt level, which significantly improves the accuracy compared to traditional detection methods. The solution has core advantages such as simultaneous monitoring of multiple components, a sample volume of only 15ml/time, fast response speed (seconds to minutes), and no need for carrier gas and consumables. It can effectively solve the problems of poor real-time performance, high cost, and complex maintenance of traditional detection methods, and provide accurate and reliable technical support for special gas production quality monitoring, clean room environment monitoring, equipment failure warning and other scenarios.

During the exhibition, the Duke Tech booth attracted many exhibitors to stop and inquire. The various forms of detection equipment displayed on site, including online, portable, and drone mounted devices, received praise for their flexible application modes and stable performance. The team had in-depth exchanges with core customers in the Haohua gas and semiconductor industries, as well as experts from research institutions, and reached multiple preliminary consensuses on issues such as technical cooperation and scenario implementation. At the same time, they actively participated in industry technology forums to accurately grasp the policy orientation and market demand of the special gas industry.

This exhibition not only demonstrates Duktech's independent innovation strength in the field of laser photoacoustic spectroscopy monitoring technology, but also solidifies the company's industry influence in the field of special gas detection. In the future, Duktek will continue to focus on the high-quality development needs of the specialty gas industry, deepen core technology research and application expansion, launch more high-performance and low-cost domestically produced detection equipment, provide better gas analysis solutions for multiple fields such as semiconductors, power, and environmental protection, and help the industry develop safely and efficiently.
