Scope

This document specifies a method for the quantitative determination of total iodine in infant  and adult nutritional formulas using ICP-MS.[1] The method is applicable for reconstituted final products containing  0,5 µg/100g to 1 500 µg/100g total iodine  and for ready-to-feed products with total iodine concentrations from 2,5 µg/100 g to 1 000 µg/100 g.
Using various infant formula and adult nutritional products, the method was subjected to an interlaboratory study. Levels of iodine obtained ranged from 3,47 µg/100 g to 124 µg/100 g. For all precision data related to the interlaboratory study, see Table A.1 located in Annex A.
