What documentation should accompany XRF results?

Having complete documentation with XRF results is essential for traceability and reliability. The measurements aren’t meaningful on their own; they must be tied to how the analysis was performed and how trustworthy the instrument is at that moment. Instrument settings describe the operating conditions used during the run—tube voltage, current, filters, geometry—factors that directly affect signal intensities and calculated concentrations. Calibration history shows that the instrument has been checked against known standards and remains within acceptable performance limits, which is what gives the results credibility. QA/QC results provide ongoing evidence that the analyzer is producing accurate and precise data, by including checks with blanks, standards, or replicates. Sample IDs ensure the data can be traced back to the correct item, preventing mix-ups. Measurement times reflect dwell times or number of scans, which influence precision and detection limits. Reporting units and uncertainties define how results are expressed and the level of confidence in them, enabling proper interpretation and comparison. Providing only final numbers would omit the context needed to assess validity, while maintenance dates or an operator’s signature alone don’t establish data quality. This full set of documentation ensures the results are traceable, defensible, and usable.
