Several nebulizers of concentric, cross-flow, Vee, frit and ultrasonic types have been compared in terms of signal-to-noise ratio (for both analyte and background signal), uptake rate, efficiency and memory effects. Especially, the dependence of these figures of merit at gas flow rates below 0.81 min −1 is investigated so as to allow an evaluation of these nebulizers for use together with low consumption torches in ICP-AES. This study was done mainly with a 56-MHz ICP, but additional measurements for a 27-MHz indicate that the results are applicable to a 27-MHz system.
