€85,00–€185,00 + taxes as applicable
This International Standard specifies a method for the quantitative determination of total iodine in infant formula and adult nutritional formula. The method is applicable to the measurement of total iodine in infant formula and adult nutritional formula from 0,5 μg/100g to 1 500 μg/100g reconstituted final product and for ready-to-feed products from 2,5 μg/100 g to 1 000 μg/100 g using ICP-MS.
Using various infant formula and adult nutritional products, the method was subjected to an interlaboratory study. Levels obtained ranged from 3,47 μg/100 g to 124 μg/100 g.
