Iron Isotope Ratios in Human Whole Blood by PlasmaQuant® MS
18 October 2017

Fe isotopic analysis by ICP-MS is a real analytical challenge because of the numerous and severe isobaric and polyatomic interferences on the four stable isotopes. This study combines the techniques of cool plasma and collision/reaction cell to completely eliminate polyatomic interferences and achieve the necessary precision and accuracy in the determination of Fe isotopes to distinguish between male and female whole blood samples.
