LUO Xiao-gang, QIU Ming-li, HOU Chang-jun, et al. Design on gas detection system based on porphyrin sensor[J]. 2010, 29(12): 108-110+120. DOI: 10.13873/j.1000-97872010.12.040.
A fast gas detecting system based on porphyrin sensor is designed to make up the deficiencies in traditional gas detecting methods.Fluid simulation in reaction room indicating that the detecting results are comparable.The principle of the system is to collect and store images of porphyrin sensor before and after the reaction with gas
and the changed color information can be obtained to match the records in database.The results prove the system can distinguish various harmful gasses accurately with a quick response.
