Autonomous and controllable: the breakthrough year of gas analysis instruments
行业资讯 2025-05-17 — 阅读
“ Driven by the intensification of global geopolitical competition and the strategy of independent and controllable high-end instruments, the gas analysis industry has ushered in a “golden window period” of localization substitution. Faced with the dilemma of high cost of imported equipment and limited after-sales maintenance, domestic enterprises have broken the long-term market monopoly and achieved a leap from “following” to “running in parallel” in high-end application scenarios such as semiconductors and new energy, relying on breakthroughs in underlying technologies such as optical detection and core sensors. ”
The tariff game is forcing localization, and high-end instruments are breaking the bottleneck.
Due to the dual impact of the escalating tariff game between China, the United States, and Europe, as well as supply chain disruptions, the procurement and maintenance costs of high-end imported gas analysis instruments have sharply increased. Many domestic enterprises have been trapped in a passive situation of “unable to afford, repair, or replace”. This severe external environment is forcing gas analysis instruments to shift from a “strategic option” to a “necessity” that concerns the survival of enterprises.
In this context, domestic leading enterprises are accelerating their breakthrough. Represented by Sifang Optoelectronics, local manufacturers have independently developed core modules such as laser Raman spectroscopy (LRD) and tunable diode laser absorption spectroscopy (TDLAS), and launched a full spectrum solution that benchmarks the performance of international mainstream brands. These domestically produced equipment not only achieve an international standard of ± 1% F.S. in detection accuracy, but also have successfully achieved domestic substitution in large-scale projects such as metallurgy and petrochemicals with significantly reduced procurement costs and fast response localized services, reshaping the industry’s discourse power.
Various optical technologies are flourishing, with Fourier transform infrared and laser spectroscopy becoming the mainstream
The current gas analysis technology landscape shows a clear trend towards “optics”. Traditional point sensors are gradually being replaced by optical technologies that can achieve non-contact, long-distance, and multi-component synchronous detection.
Visualization breakthrough of Fourier transform infrared spectroscopy (FTIR): Hanwei Technology and Aerospace Hengjia have launched a Fourier transform infrared gas analyzer, which endows gas monitoring with the ability of “infrared fingerprint recognition”.. This technology can perform qualitative and quantitative integrated analysis of dozens of gases such as volatile organic compounds (VOCs) and sulfides within a kilometer range through passive infrared imaging, and visualize invisible gas plumes in real time. This “visible, accurate, and far-reaching” characteristic quickly makes it a powerful tool in the field of unorganized emission tracing and emergency firefighting in chemical industrial parks.
Trace detection limit of laser spectroscopy technology: In fields such as semiconductor manufacturing that require extremely high purity, the trace gas analyzer launched by the subsidiary of Focus Technology, relying on leading cavity ring down spectroscopy technology, has pushed the detection limit to the ppt (parts per trillion) level.. This ultra-high sensitivity monitoring capability accurately meets the strict control requirements for trace pollutants such as ammonia and hydrogen chloride in the wafer manufacturing process.
Seize the semiconductor and new energy track and build full chain detection capabilities
With the expansion of global semiconductor production capacity driven by AI and data centers, as well as the explosive growth of the new energy industry, gas analyzers are showing huge market growth in emerging tracks.
Precision quality control in the semiconductor field: Faced with a global semiconductor testing system market of over 9 billion US dollars, domestic instruments have deeply penetrated into the core quality control process.. The ICP-MS/MS system launched by Focus Technology has successfully constructed a comprehensive solution for trace impurity analysis covering high-purity wet chemicals, photoresist, and metal residues on wafer surfaces. It has been successfully imported and validated in multiple leading domestic wafer manufacturing enterprises, laying a solid safety barrier for the industry chain.
Exclusive monitoring in the field of new energy: In the production process of lithium batteries, dedicated gas detectors with high anti-interference and fast response capabilities have become standard equipment for detecting harmful gases such as carbonates and hydrogen fluoride produced by electrolyte evaporation, as well as the extremely high detection requirements for hydrogen gas leakage in hydrogen storage and transportation, providing protection for the safe expansion of the new energy industry.
AI is deeply integrated with edge computing to reshape field monitoring efficiency
The deep cross fusion of artificial intelligence and microsensor technology is redefining the field monitoring boundaries of gas analysis equipment. The roadmap released by the Intelligent Grid Research Institute of Tsinghua University shows that the embedding of AI algorithms has significantly improved the accuracy of fault warning.
In scenarios such as portable gas analysis in oil, the recognition speed of convolutional neural network models for characteristic gases such as acetylene has been reduced to 0.8 seconds per sample. Meanwhile, the application of edge AI chips has increased the data processing capability of a single device by 5 times, significantly reducing reliance on the cloud. With breakthroughs in low-power technologies such as flexible solar thin film charging, the new generation of miniaturized monitoring devices has achieved a qualitative change from “functional satisfaction” to “experience optimization” while maintaining unlimited battery life, driving the industry into a high value-added competition stage.
Conclusion
Under the dual stimulation of external pressure and internal innovation, the gas analysis industry has undergone a profound industrial transformation. From the domestic substitution that breaks the import monopoly, to the widespread application of optical technologies such as Fourier transform infrared and laser spectroscopy, and to the deep empowerment of cutting-edge fields such as semiconductors and AI, China’s gas analysis industry is building a new ecosystem of global perception, precise industrial safety, and environmental monitoring with independent and controllable hard core strength.
