ISO 20647 | IDF 234: 2015 - Infant formula and adult nutritionals - Determination of total iodine - Inductively coupled plasma mass spectrometry (ICP-MS)

Publication description

This International Standard specifies a method for the quantitative determination of total iodine in infant formula and adult nutritional formula.[1] 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.
