Iodide is an essential element in the human body to make thyroid hormone. Iodide was analyzed using HILICpak VT-50 2D, a polymer-based HILIC mode column, with LC/MS detection. High acetonitrile concentration in the eluent is suitable for the analysis with higher sensitivity and selectivity than ion chromatography.
