Test Summary:
| Test | Reported Units | What does this test measure? |
| Iodide | µg/100g | This method is used to detect the iodized form of iodine, typically added as iodized salt (KI). Testing measures the amount of ions (I-) and reports as iodide. This method does not detect native iodine in the sample matrix or sources of iodine that would dissociate into anything other than I-. |
| See test summaries below for other tests related to “Iodide.” | ||
| Iodine by ICPMS | ppb | This method measures multiple forms of Iodine (including Iodide, Iodate and elemental iodine) via ICPMS and reports as Total Iodine. This method cannot distinguish between Iodine species. |
| Iodine Value | cg/g | This method measures the double bonds in fats and oils, or the amount of unsaturation in a fat or oil. This is considered a rancidity test and is only tested on fats and oils. |
Equipment:
Iodide Ion Selective Electrode by Hanna Instruments
Reportable Units:
µg/100g
Turnaround Time:
7 – 9 Business Days
Is rush testing available?
Yes
Method Reference:
AOAC Official Method 992.24
Method Description:
Iodide is extracted from the sample matrix using acetic acid and homogenization. The amount of iodide is determined using the known addition technique. The difference in electrode potential is calculated from the extracted sample and the addition of a known standard of 1 mg/L. This electrode potential change is converted into an iodide concentration utilizing the linear range of the ion selective electrode.
