Abstract

Trace elemental analysis technologies using atmospheric plasma sources have been used in many fields such as environmental analysis, semiconductor industry and medicine. Since 1970's, argon inductively coupled thermal plasma (ICP) has been used as ionization or excitation source for atomic emission spectrometry or mass spectrometry because of the excellent power of detection and the ability to measure isotope ratios. However, it is difficult to determine high ionization potential elements such as halogens and rare gases by using argon plasma. In order to overcome argon ICP, many types of atmospheric plasma sources have been developed and investigated. Furthermore, some kinds of sample introduction systems have been developed and applied with the plasma sources. As a result, sub-pg/mL of detection limits for almost all elements are realized.
