Solid sampling by electrothermal vaporization in combination with electrostatic particle deposition for electrothermal atomization multi-element analysis

摘要: A novel combination of electrothermal sample vaporization from one furnace and electrostatic deposition the aerosol on a L'vov platform in second graphite used for subsequent atomization multi-element analysis is described. The generated by liquid as well solid primary samples transported to an Ar gas flow piped into through dosing hole via glass capillary mounted autosampler arm continuum source coherent forward scattering spectrometer. obtained electrostatically corona-like discharge. near quantitative produced allows optimal direct determination transport efficiencies comparing signals measuring directly with spectrometer transferred deposition. Over all transfer up 30% are observed samples. Results sampling BCR CRM 189 Wholemeal flour good agreement certified values.
