| Outline of Final Research Achievements |
Tubular filter collection followed by on-line elution induction coupled plasma mass spectrometry (ICP-MS) measurement was developed as a technique for multielemental analysis of PM2.5, ensuring the sample collection for high-temporal-resolution analysis and the highly-sensitive analysis of the elements. Tubular filter collection ensured that the sample was enriched in a narrow space (decreased to 1/100 of that traditionally used), permitting the effective elution of the elements using a little bit of eluent for the measurement by ICP-MS. The on-line elution followed by ICP-MS ensured the highly-sensitive analysis of elemental signals due to the transient high concentration of the elements in the eluent.
