Outline of Final Research Achievements |
A throughput higher than an ion mobility spectrometer of mass separated atmospheric pressure ion production has been demonstrated with a Gerdien condenser, and the possibility of applying the system to improve soil and irrigation water quality at the site of agricultural production. A compact analysis system has been successfully assembled with a radio-frequency driven atmospheric pressure plasma source, which was capable of evaluating the condition and components contained in the atmosphere. The performance of the analysis system was studied and the surface of the ion detection electrode of a Gerdien condenser was found aged with the time constants of the order of ten minutes. A substantial improvement in stability for atmospheric pressure ion production was obtained by increasing the discharge frequency of an AC discharge power supply. The produced flow with nitrogen ions was guided to radish seeds on a hydroponic bed to examine effects due to ions on the seeds’ growth.
