High Sensitivity Analysis of 41K Abundances in Refractory Inclusions
Abstract
We have used the high sensitivity of SHRIMP ion microprobes with 40Ca+ count rates of >100 MHz to assess the analysis of the 41Ca-41K system. At these count rates, the background can be quantified and interferences monitored dynamically during analysis.
