Main Research Achievements
Did you know that contaminants in natural gas pipelines, such as H₂S and H₂O, damage the pipelines? Our developed instrument can measure these components, allowing them to be removed from the gas. Based on this PA measurement technology, hundreds of PA systems are now in operation at oil industry sites worldwide.
The gas composition of exhaled breath carries information about a person's biological condition, enabling rapid and non-invasive diagnostic procedures. We collaborate with medical research groups to develop gas concentration measurement instruments for human and animal models. Our measurement systems can continuously determine CH₄ and N₂O concentrations in exhaled air with a resolution of a few seconds and below ppmV levels.
We have developed a system for determining NO, NO₂, NH₃, CH₂O, and N₂O concentrations in vehicle exhaust, which we test on our own engine test benches as well as those at AUDI Hungaria Zrt. and Széchenyi University. Our research group is working on a fast and precise vehicle emissions measurement device that is portable, can operate on a test bench, and can be installed in vehicles. The instrument automatically measures emissions in real-time, with second-level resolution and without the need for sampling, utilizing the entire gas flow for analysis.
We also conduct detailed physical-chemical characterization of soot aerosols in exhaust gas using our own specialized and state-of-the-art measurement tools. This unique capability allows us to study the effects of soot aerosols on radiative balance and human health, contributing to a deeper understanding of vehicle emission-related environmental impact.
We have identified relationships between real-time, wavelength-dependent photoacoustic responses of atmospheric soot aerosols and their other physical-chemical markers. These findings provide new methods for real-time air quality monitoring and source identification.
One of our newest research areas involves developing a measurement unit for disaster response. This system can determine whether there are survivors trapped under rubble or detect gas leaks after an earthquake, ensuring that neither rescue workers nor animals are put at risk.
Additionally, in agriculture, we conduct novel in situ PA measurements with fast response times to monitor fertilizer-related emissions. We are developing instruments capable of measuring target gas components near the soil, a few meters above the ground, and even mounted on drones with high accuracy.
