Abstract : The use of a microarc atomizer as a device for microsample introduction into the ICP(Inductively Coupled Plasma) is described. The microarc, a high-voltage, low-current, pulsating dc discharge, efficiently vaporizes desolvated, discrete microvolumes of sample solution into the plasma. The microarc-ICP combination exhibits relative detection limits and working curves comparable to those of other methods of sample introduction but functions with sample volumes in the 0.5 - 1.0 microliter range. Matrix and ionization interference effects are absent or trivially overcome. Computer control of the instrument adds simplicity of operation. (Author)
