Conclusion

While LA-ICP-MS has many benefits over traditional solution based ICP-MS methods for measuring major and trace elements in various carbonate objects, current analytical setups can be inflexible with regards to laser firing duration. Our freely available LABLASTER package implements methodological improvements to refine analytical workflows.
The endPoint function that implements these improvements is compatible for use within loops, aiding high-throughput and repeatable data cleaning of carbonate materials that are ubiquitously used in past climate reconstructions, geochemical ecology and evolution studies and cryptic taxonomic distinctions.
