What is a key purpose of documenting calibration history in XRF results?

Documenting calibration history provides traceability for measurement results and QA/QC status. By keeping records of when calibrations were performed, which standards were used, instrument settings, drift checks, QC sample results, and any corrective actions, you can show that the instrument was in control and producing valid, reproducible data at the time of analysis. This supports audits, regulatory compliance, and the ability to investigate or reproduce results later. The other options don’t fit because calibration history isn’t about advertising the instrument brand, sharing information with competitors, or determining reagent shelf life.
