Microwave Induced Combustion (MIC) followed by F-ISE or IC
- Applied for halogens in infant formula (mainly Br and I)
- Methods for fluoride in other food matrices (spices, plants)
•
Automatic standard addition/F-ISE
•
Specific extraction/Dialysis/Microwave digestion and IC
- Specific supplier IC equipment (e.g. in line dialysis, in line SPE)

•
New promising methods (but not yet applied for IF) that potentially could meet
current SMPR are mainly based on:
- Microwave digestion and F-ISE or spectrophotometry detection
- Derivatization and GC-FID/MS
•
Codex requirement : F content < 100μg/100 kcal
(< 65μg/100g* reconstituted IF
)
BUT
AUS-NZ has one specific requirement: claims needed for
50 μg/100 g
in
powder (corresponding to current LOQ=5 μg/100 g in SMPR)
•
Proposal for next step
:
1. If only Codex standard maximum limit* is followed: revise SMPR with higher LOQ
(e.g. 50-65 μg/100g)
2. If SMPR is maintained: reopen call for methods to evaluate new methods using
ISE, IC or GC with specific sample preparation (Microwave digestion, specific
buffer extraction
