Inductively Coupled Plasma Emission Spectrometry

Inductively Coupled Plasma Emission Spectrometry

A test method of quantitative identification of the elements, Aluminium, Silicon, Sodium, Vanadium, Nickel, Iron, Calcium, Zinc and Phosphorus in residual fuel oils.

A weighted test sample is prepared first by Ashing. The residue is fused with a buffer and diluted with water. The solution is then aspirated in the plasma if the Inductively Coupled Plasma Emission Spectrometer (ICPES) and the emission radiation of the resonance lines of the elements under analysis is measured and compared to a calibration curve constructed by standard calibration solutions.

This method of elements determination can also be performed with the Atomic absorption spectroscopy AAS.
