Which statement best describes the role of QA/QC results in XRF analysis?

Quality control results in XRF analysis are used to confirm that measurements stay accurate as the instrument runs. By regularly checking with standards, blanks, and QC samples, you compare observed values to known values within predefined limits. This helps you catch drift in sensitivity or other instrument issues early, so you can correct them before they corrupt sample results. QA/QC supports confidence in the data rather than determining a sample’s composition—that’s what the raw sample measurements do. Calibration records are still needed and QA/QC works with them; QA/QC does not replace calibration. And QA/QC is essential, not optional, for reliable results.
