Popis
BS EN ISO 11212-3:1997
This standard BS EN ISO 11212-3:1997 Starch and derived products. Heavy metals content is classified in these ICS categories:
- 67.180.20 Starch and derived products
This part of ISO 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.
