ISO 11212-4:1997 Starch and derived products -- Heavy metals content -- Part 4: Determination of cadmium content by atomic absorption spectrometry with electrothermal atomization
standard by International Organization for Standardization, 03/01/1997

Full Description
This patt of ISO 11212 specifies a method for the determination of the Cadmium content of starch, including derivatives and by-products, by atomic absorption spectrometry with electrothermal atomization.
The number of Parameters for the procedure involved in the electrothermal atomization is far larger than in flame atomization; it is thus impossible to propose a comprehensive method likely to ensure the attainment of satisfactory results on all types of apparatus currently available. Esch analyst should therefore optimize the conditions of use of his/her own apparatus on the basis of general or particular instructions.
