ASTM E2594-20,Standard Test Method for Analysis of Nickel Alloys by Inductively Coupled Plasma Atomic Emission Spectrometry (Performance-Based).
ASTM E2594-20 describes the inductively coupled plasma atomic emission spectrometric analysis of nickel alloys, such as specified by Committee B02, and having chemical compositions within the following limits.
ASTM E2594-20 has only been interlaboratory tested for the elements and ranges specified.
Samples are dissolved in a mixture of mineral acids andthe resulting solutions are measured using inductively coupledplasma atomic emission spectrometry.
Practice El479 describes the typical interferences encountered during the inductively coupled plasma spectrometric analysis of metal alloys. The user is responsible for ensuring the absence of or for compensating for interferences that may bias test results obtained using their particular spectrometer.
The use of an internal standard may compensate for the physical interferences resulting from differences between sample and calibration solutions transport efficiencies.
