The breakthrough path of "localization" and "digitalization" in the gas analysis industry
行业资讯 2025-02-10 — 阅读
“2025 Since the beginning of the year, the gas analysis industry has entered a critical window period of technological breakthroughs and industrial restructuring driven by the dual needs of safety and energy transformation. From precise warning in coal mines to quality control in the hydrogen energy industry chain, gas analyzers are accelerating their transition from traditional “alarm” labels to high-precision, domestically produced, and intelligent “industrial perception nerves”. ”
1. Policy and necessity resonance, safety monitoring moves towards the “sub ppm level” precision era
At the beginning of 2025, the pain points in the field of safety production are forcing gas detection technology to evolve towards * * precision. Traditional electrochemical sensors are unable to meet the current safety red line requirements for complex industrial scenarios such as coal mine spontaneous combustion and chemical leakage due to their susceptibility to temperature and humidity interference and difficulty in real-time monitoring.
The * * * achievements disclosed by the team of the Chinese Academy of Sciences Hefei Institute of Physical Sciences in April 2025 are a typical epitome of this trend. The fully laser gas monitoring device developed by it has successfully overcome the interference problem under high concentration methane background through the pioneering spectral adaptive algorithm, achieving precise capture of key indicator gases (such as carbon monoxide and ethylene) in the early stage of coal mine spontaneous combustion at the sub ppm level (below one millionth). This technology has been deployed in more than ten coal mines in Anhui, Xinjiang, and other places, and can provide a warning of potential spontaneous combustion risks 2-3 days in advance. This marks a new stage in the gas monitoring of high-risk industries in China, from “post alarm” to “precise prediction in advance”.
2. The wave of localization is accelerating, and core equipment is breaking the bottleneck.
For a long time, the high-end gas analysis instrument market has been monopolized by imported brands. But by 2025, with the advancement of * * *’s energy security strategy, domestic substitution has penetrated from “pipe hardware” to the core fortress of “precision instruments”.
In May 2025, the “Smart Eye” natural gas quality analysis equipment independently developed by * * Pipeline Network Group was successfully selected as the first major technical equipment in the energy field by * * Energy Bureau. This equipment has broken over 95% of foreign technological monopolies, with a localization rate of up to 99%. With only a very small amount of samples, it can quickly detect 14 components in 5 minutes, and its technical indicators are even better than similar international products. At the same time, in the emerging field of hydrogen energy, Shanghai Huaai Chromatography launched the world’s first “hydrogen energy quality mobile detection vehicle” in July 2025, which also fills the gap in domestic hydrogen on-site detection and standard sampling equipment. These breakthroughs not only significantly reduce procurement and maintenance costs, but also provide solid support for the independent and controllable development of China’s energy industry chain.
3. A variety of technical routes are emerging, with laser and Raman spectroscopy becoming the mainstream
In the technology landscape of 2025, optical detection technology will replace traditional technology as the mainstream in the market due to its advantages of anti-interference, long lifespan, and multi-component synchronous analysis.
Laser spectroscopy and laser Raman technology experienced an explosion this year. The laser Raman gas full component online rapid analysis solution launched by Sifang Instrument fills the technical gap of commercial products in China. It can synchronously and quickly analyze the concentration and calorific value of nearly 20 gases, and is widely used in the coal chemical and petrochemical industries. In terms of special gas detection, the laser photoacoustic spectroscopy technology demonstrated by Beijing Duktek has pushed the detection accuracy to the ppb (one billionth) or even ppt (one trillionth) level, without the need for carrier gas and consumables, perfectly meeting the strict requirements of semiconductors and aerospace for ultra-high purity gases.
4. Deep integration of AI and the Internet of Things to build a new ecosystem of “smart perception”
The gas analyzer of 2025 is no longer isolated hardware, but deeply integrated into the ecosystem of artificial intelligence and the Internet of Things.
In the field of civil and commercial gas safety, Sifang Optoelectronics has released the domestic * * * “Infrared Household and Catering Gas Detector” group standard, which clarifies the new height of infrared detectors in anti-interference and stability. The four channel infrared methane sensor developed by it eliminates cross interference through multi wavelength regression algorithm and has a service life of over 10 years. On the industrial side, intelligent analyzers equipped with AI algorithms can combine historical data to predict gas concentration trends, and upload data in real-time to the cloud through 5G networks, achieving a digital transformation from “passive monitoring” to “active warning”, and from “manual inspection” to “remote intelligent control”.
Conclusion
Looking back at the node of 2025, the gas analysis industry is undergoing a profound transformation from “following” to “leading”, and from “single hardware” to “smart ecology”. With the continuous breakthroughs in domestic core technologies and the deep empowerment of AI technology, gas analyzers will continue to serve as the “golden eyes” for industrial safety and energy transformation, safeguarding high-quality development.
