Primary Institution: Nankai University
Hypothesis
The study investigates the effectiveness of a flow injection analysis (FIA) method using a galvanic detector for measuring nitrogen dioxide.
Conclusion
The FIA method is simple, rapid, and extends the measuring range of the galvanic detector for nitrogen dioxide detection.
Supporting Evidence
- The FIA method allows for reproducible peak signals without the need for steady state measurements.
- The measuring range of the galvanic detector was extended to 500ppm for nitrogen dioxide.
- The relative standard deviation for 200ppm nitrogen dioxide was found to be 2.4%.
Takeaway
This study shows a new way to quickly measure nitrogen dioxide in the air using a special detector that works with a flow of gas.
Methodology
The study used a flow injection analysis system with a galvanic detector to measure nitrogen dioxide concentrations in a gaseous sample.
Limitations
The method may be influenced by the presence of other gases, which can interfere with the measurements.
