A particle collector that allows high time resolution monitoring of particulate matter was fabricated and coupled with an ion chromatograph for online analysis of particulate ions in the atmosphere. The system was applied to the atmospheric observation for over a month in Tokushima, Japan. The average particulate anion concentrations were 6.42 nmol m-3 for Cl-, 18.8 nmol m-3 for NO-3 , and 22.1 nmol m-3 for SO24-. The atmospheric particle collection efficiency was more than 98.4%, and the continuous observations were successfully achieved without problems.
