| Outline of Final Research Achievements |
From a few days to one week, real time monitoring of APs was carried out with an interval of 5 min. Recovery of elements was calculated by dividing the real-time monitoring data by the filter-collection data. The recovery of easily vaporized elements (As, Se, Sb etc.) was larger than 100%, and that of hardly vaporized elements (Sr, Zr, Th etc.) was less than 100%. It is likely that smaller particles, on which easily vaporized elements were enriched, were not collected on filters. Whereas, larger particles could not be decomposed completely in plasma and that is a reason why the recovery of hardly vaporized elements was less than 100%.
