This part of IS0 11212 specifies a method for the determination of the lead 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. Each analyst should therefore optimize the conditions of use of
his/her own apparatus on the basis of general or particular instructions.
Diese ÖNORM beschreibt ein Verfahren für die Bestimmung des Cadmiumgehaltes von Stärke, Stärkeprodukten und Nebenprodukten mittels Atomabsorptions-Spektrometrie im Graphitrohrofen.
