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.

Application Notes

System configuration

For the analysis of iodide we selected the Flexcell electrochemical cell with exchangeable Boron Doped Diamond working electrode. The HyREF is maintenance free. The ALEXYS system comprises the following parts:

  • AS 110 autosampler, cool
  • P6.1L HPLC pump
  • Clarity data acquisition software
  • DECADE Elite electrochemical detector
  • Flexcell with BDD WE, HyREF ALEXYS for Iodide
