Operational data for an XRF can be found in which document?

The Performance Characteristic Sheet (PCS) is a critical document that contains essential operational data for an XRF (X-ray fluorescence) instrument. This document outlines the instrument's performance specifications, detection limits, calibration standards, and operational parameters necessary for accurate analysis. It serves as a comprehensive guide to understanding how the XRF should perform under various conditions, which is vital for ensuring reliable and valid results during lead risk assessments.

While the User Manual provides instructions for proper operation and maintenance of the XRF, it does not typically include detailed performance metrics. The Calibration Report is specific to the calibration process of the instrument, reflecting its accuracy at that point in time but lacking broader operational data. The Inspection Report is related to the overall assessment and condition of the instrument, but again, it does not contain the specific performance characteristics used in everyday operation. Thus, the Performance Characteristic Sheet is the most relevant document for operational data concerning an XRF.
