Studies are presented describing direct, clog-free production of high density finely dispersed aerosols from highly complex samples through use of a special nebulizer design based on principles first developed by R. S. Babington. Application of this technique to sample introduction for atomic absorption spectrometry is described for matrices of combined high suspended solids content, increased viscosity, and elevated salt concentration. Cu and Zn are determined in whole blood, urine, seawater, evaporated milk concentrate, and tomato sauce with minimal sample preparation.
