Iodide in milk

ALEXYS Anions Analyzer

 

 

 

 

Iodine is an essential trace element for humans. It is a component of the thyroid hormone thyroxin, which regulates the body’s metabolic state and the growth and development in children. The dietary uptake of sufficient trace amounts of iodide is therefore necessary for mental and physical development. Important sources of Iodide are seafood, diary products, iodized table salt and proc-essed foods like iodized bread.

The ALEXYS Iodide Analyzer uses a Diamond electrode. Conductive diamond has several advantages over conventional electrode materials such as a wide potential window in aqueous solutions, excellent chemical inertness and stability. The chromatogram shows iodide in low fat milk.
