“…Therefore, the system is ideally suited for field applications due to its inherent portability. The portability advantage of the tungsten coil atomizer has been demonstrated previously for atomic absorption spectrometry (Nó brega et al 1995;Sanford, Thomas, and Jones 1996;Hou et al 2001;Ribeiro, Arruda, and Cadore 2002). A WCAES system, however, is even easier to transport into the field, since no external radiation source is required.…”
