In a renowned university's materials science laboratory, a cutting-edge study on the combustion characteristics of graphite is in full swing. The core of the research lies in precisely controlling combustion conditions to explore the efficiency and product composition of graphite under different environments.


One of the major challenges encountered during the experiment is accurately detecting trace amounts of gases — carbon dioxide (CO₂) and carbon monoxide (CO) — produced during combustion in a small pipeline. Due to the experimental design, the gas flow rate is extremely low, just 30 ml/min, which places unprecedented demands on the sensitivity, accuracy, and stability of the gas detection equipment.


Zetron responded swiftly to this scientific challenge, assembling a dedicated team of experienced engineers and researchers. After in-depth analysis and repeated testing, they delivered a customized low-flow gas detection solution.


At the heart of this solution is the MS600 gas analyzer, enhanced by a custom micro-flow pump, allowing high-precision detection of ultra-low gas volumes.
