| Research Abstract |
An automated analysis system has been developed for measuring perchlorate concentration in atmospheric aerosol. The sensitivity is increased by a factor of 7.7 with a Nafion membrane tube based post-column concentration technique. The proposed system has been successfully operated at Tokushima, Japan. The limit of detection (LOD) is 0.35 ng/mm^<3> for 3 hours sampling cycle. The perchlorate concentration in the atmospheric aerosol ranged between LOD to 18.6 ng/mm^<3>.
