Determination of Ultralow Iridium Concentration in Small Geological Samples: Isotope Dilution Coupled with Multiple Ion Counting Inductively Coupled Plasma Mass Spectrometry Concentration of Ir in natural samples can provide useful information for tracing a variety of geological and planetary processes, however, efficient, sensitive, and precise analysis of Ir contents remains challenging especially for crustal samples that are highly depleted in Ir (i.e., at pg g-1 level).
