Quantitative determination of bromine and iodine in food samples using ICP-MS.
Trace concentrations of bromine and iodine in food samples and certified reference materials (CRMs) were determined by an inductively coupled plasma-mass spectrometry (ICP-MS) technique after low-power microwave digestion and extraction into an aqueous quaternary ammonium hydroxide solution. The recovery after sample preparation was quantitative. The internal standard for the measurement of the...
متن کاملThe Determination of Iodine in Food with the ELAN DRC-e ICP-MS
Introduction Iodine is essential for the production of thyroid hormones. These hormones stimulate metabolism in the body, as well as mental growth and development. The recommended daily iodine intake is 0.1-0.2 mg, with the most common sources of iodine being fish, seafood, milk and food supplements. The determination of iodine in food has always been difficult due to the low concentrations (mg...

متن کاملThe ultratrace determination of iodine 129 in aqueous samples using the 7700x ICP-MS with oxygen reaction mode
Determination of the radionuclide iodine 129 using ICP-MS has been improved by the use of an Octopole Reaction System (ORS) ICP-MS, operated in oxygen cell mode. Oxygen reaction gas removes the background signal at m/z 129, which is due to the presence of Xe as an impurity in the Ar plasma gas and to the polyatomic ion IH2. NIST SRM standards with different 129I/127I ratios and at multiple conc...
