Ferronickel. Determination of trace-element content by electrothermal atomic absorption spectrometric method - Determination of tellurium content Ingestion-build-242630 Threshold data1 Scope This part of ISO 11438 specifies an electrothermal atomic absorption spectrometric method for the determination of tellurium in the range of 0,3 g t to 2,0 g t in ferronickel, according to the principle of standard additions. The general requirements concerning the apparatus, sampling, dissolution of the test sample, procedure, calculation and test report are given in ISO 11438 1.
