Agilent 7700x ICP-MS Ultratrace Determination of Iodine-129 Application Note

About this manual

The document details a method for measuring the radionuclide iodine-129 (I-129) using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The study utilizes an Agilent 7700x ICP-MS equipped with an Octopole Reaction System (ORS) cell operated in oxygen reaction mode. This setup effectively removes background signals caused by Xenon impurities and polyatomic ions, enabling high-sensitivity detection without sample preparation.
