| Outline of Final Research Achievements |
In order to increase the sensitivity of ICP atomic emission spectrometry, an electrostatic shield was applied. By grounding the shield and optimizing plasma operating parameters, background equivalent concentration (BEC) of several elements was improved approximately 4 to 10 times compared to that obtained with a conventional method. The close examinations of intensity distribution along a plasma radius and emission spectra showed that the improvement of BEC was found to be brought by remarkable decrease of background intensities. Electrostatic shields made of different materials were applied to ICP mass spectrometry and the effects of the materials were systematically investigated. As a result, SUS304 was found to be superior in sensitivity, durability and cost.
