The use of a new MultiNeb® nebulizer for the on-line isotope dilution inductively coupled plasma mass spectrometry (OID-ICP-MS)

Matraz aforado

The new MultiNeb® enables the on-line sample spiking by means of the simultaneous introduction of the spike (i.e., isotopically enriched standard) and the sample (i.e., natural isotopic composition) solutions and an effective mixing between them, since the mixing takes place under turbulent conditions of high pressure at the inner part of the tip of the nebulizer. An OID-ICP-MS methodology based on the MultiNeb® is presented. The target is to improve the productivity of the routine laboratories in the analysis of samples with a complex matrix by the implementation of the MultiNeb® in the on-line ID-ICP-MS analysis.
