Assessing Matrix and Nonmatrix, Single, and Multipoint Calibration of Trace Elements Using LA‐ICP‐MS on a Tropical Speleothem
Our experiments provide a proof of concept on the conventional setup of standards during LA-ICP-MS speleothem analysis. We suggest the use of at minimum a 2-point (silicate plus carbonate or carbonates) calibration curve that crucially bracket the range of sample concentrations rather than relying on a 1-point silicate standard that does not bracket the sample concentration. Finally, our results have implications for both speleothem studies that use LA-ICP-MS analytical techniques and additional carbonate archives.
