A technique to dilute a sample after nebulization for sample introduction into an ICP. A flow of argon gas is added to the sample aerosol generated by the nebulizer before the aerosol is reaching the torch injector. When keeping the total flow to the injector constant, this has the effect of reducing the sample’s solvent loading to the plasma, so it can tolerate much higher total dissolved solids.
