AN222: Determination of Parts-Per-Trillion Concentrations of Strontium by Pre-Concentration with Ion Chromatography and Suppressed Conductivity Detection
DescriptionRadioactive isotopes of strontium (90Sr and 89Sr isotopes) are byproducts of nuclear power plant reactions. 90Sr monitoring is needed because 90Sr can displace calcium in bones and teeth, resulting in long term exposure and subsequent increased cancer risk. Ion-exchange chromatography can be used to focus and isolate 90Sr from other isotopes that interfere with accurate scintillation determinations. Here ng/L of non-radioactive Sr as a retention time marker for 90Sr is pre-concentrated, then separated on an IonPac CS12A column, and detected by suppressed conductivity.
