- 研究成果概要
- A unique system that uses the total reactivity with ozone (RO3) has been developed for measuring biogenic volatile organic compounds (BVOCs) emitted from vegetation into the atmosphere. However, the sensitivity of the RO3 analyzer was insufficient for measuring the atmosphere in the forests. Recently, the sensitivity of the ozone monitor in the analyzer has been improved. In this study, further improvement of the analyzer was explored. As a result of reduction of noises in the detector, the detection limit of RO3 analyzer reached 0.2 x 10-4 s-1 (S/N = 3, 60-s average). After the improvement, a practical test for measuring RO3 in the forest was conducted at Tokorozawa in summer. Consequently, it was experimentally confirmed that coexisting NO can be critical as interference of measurement. This issue remains to be solved. Meanwhile, as another application of improved RO3 analyzer, temperature dependence of rate coefficients of the reaction linalool+O3 was experimentally determined successfully. The RO3 analyzer is promising for kinetic studies of BVOCs+O3 reactions.
