A rapid and sensitive method for the analysis of non-digested biological slurries with minimal dilution volumes is demonstrated. Quantification of elements at trace to macro levels is performed on 16 analytes in 70% whole blood serum with 14 of the species reported at +/- 10% and the remaining two at +/- 20%. Three nebulizers were tested for sensitivity and stability with the Burgener T2100 being recommended when the homogenization of samples is incomplete and residues of large particles may be present. Interestingly, the glass concentric nebulizer displayed higher sensitivities relative to the T2100 which seemed to be wavelength dependent and with the highest ratios occurring below 280 nm.
