Semi-automatic Gas Measurement Device Based on Fluorescent Multi-gas Sensors

This paper describes the development of a semiautomatic gas measurement device presenting potentially a broad range of applications, noteworthy in the agricultural sector. Nonreversible fluorescent molecular sensors were designed and synthesized. Upon, integration into a hydrogel matrix with an optimal ratio of co-solvents, the sensors reacting selectively to ammonia were illuminated by excitation light to produce a concentration-correlated fluorescence emission. An automated mechanical-electrical device initiates a given gas mixture and thus simulates concentrations similar to a threshold value. The aim of this project is to develop a sensor or a low-cost method which can monitor low concentrations of harmful gases and aid in their elimination or regulation in livestock housing, barns or stables.
