China’s domestically produced high-end chromatography equipment once again achieves a new milestone! Corey Chromatography helps the Fuyang Electronic Specialty Gas Project achieve ultra-pure monitoring at the 7N level.
Recently, by Liaoning Kerei Chromatography Technology Co., Ltd. For Anhui Zhongke Haohai Gas Technology Co., Ltd. (A subsidiary of Sino-Science Fuhai Group) Fuyang Phase III Electronic Specialty Gas Project The complete high-end gas analysis system provided has been successfully delivered and installed on-site, with commissioning now underway. This project marks another milestone for Core Chromatography in... Ultra-high-purity electronic specialty gas analysis field Another meticulously crafted “turnkey” benchmark project marks a significant breakthrough in the quality control and safety monitoring of electronic specialty gases—the critical materials in the semiconductor industry chain—by domestically produced precision analytical instruments, earning deep recognition from high-end industry clients.
In high-end manufacturing fields such as semiconductors and integrated circuits, the purity of electronic specialty gases directly determines the performance and yield of the final products. Among them, Ultra-high-purity gas analysis at 7N grade (99.99999%) The project places nearly stringent requirements on the instrument’s detection limit, stability, repeatability, and anti-interference capability. Relying on its deep technological expertise and profound understanding of customer processes, Core Chromatography has tailored a comprehensive solution for this project, encompassing both an online analysis system and multiple sets of offline analytical instruments.
The core of the solution comprises an offline analysis system integrated with a positive-pressure explosion-proof analysis booth. This booth is designed strictly in accordance with Zone 2 requirements for hazardous explosive environments and is constructed from 304 stainless steel. Its explosion-proof rating reaches Exd e ib mb nC pc IIc T4 Ge, while the explosion-proof level of its internal electrical equipment is no lower than Exd IIC T4 Gb. With a maximum enclosure protection rating of IP65, the booth provides a solid guarantee for the long-term, stable, and safe operation of analytical instruments under complex operating conditions. The booth houses multiple GS2010 series gas chromatographs centrally deployed, combined with customized pre-processing units, to create a comprehensive offline analysis network covering tank farms, plant areas, and Class D workshops.
This system is capable of precisely analyzing trace impurities in ultra-pure ammonia (7N), electronic-grade carbon dioxide (6N), electronic-grade carbon monoxide (5N), food-grade carbon dioxide, and a variety of specialty mixed gases. The detection limits for key components are as low as the ppb (parts per billion) level. In particular, the ultra-pure ammonia analysis can achieve separate detection of oxygen and argon as well as independent measurement of C1-C3 hydrocarbons, fully meeting the stringent quality control standards of the electronic special gas industry. The entire system is designed to enable real-time online monitoring of critical process points in production, provide timely safety alerts, and ensure precise control over product quality.
To ensure the smooth implementation of the project, the Core Chromatography Technology team conducted multiple rounds of in-depth technical exchanges with the customer, and through a rigorous approach, ensured that the instrument performance fully met the project’s requirements. During the project implementation, the technical team efficiently completed system installation and integrated commissioning, and the equipment has been operating stably, with all key performance indicators meeting or exceeding the design expectations. The commissioning of this system will strongly support the customer in achieving intelligent monitoring of the production process, enhancing inherent safety, optimizing processes, and ensuring full-process traceability of product quality, thereby providing solid data support for building a highly reliable supply chain for specialty electronic gases.
The successful delivery of this Fuyang project not only marks a significant milestone for Core Chromatography in the strategic emerging market of electronic specialty gases, but also serves as strong evidence that domestically produced high-end analytical instruments can play a crucial role in key links of the nation’s core industrial chains. It further underscores Liaoning Core Chromatography’s transformation from a specialized equipment manufacturer into... High-end analytics solutions provider The comprehensive strength of transformation.
In the future, Core Chromatography will continue to deepen its focus on strategic industries such as semiconductors, new materials, and new energy. Guided by core needs—including ultra-high-purity material analysis and process safety monitoring—we will keep innovating and deliver comprehensive, more advanced, and more reliable analytical technology solutions to support the high-quality development of China’s high-end manufacturing sector.
