The XRF Performance Characteristics Sheet (PCS) provides information necessary to conduct what kind of inspection?

• A. A general safety inspection of a facility
• B. An environmental air quality assessment
• C. An inspection of lead-based paint using specific XRF instruments
• D. A laboratory analysis of soil samples

Answer: (D)

The XRF PCS gives the performance data of the instrument that you rely on to plan and execute an analysis, especially in a controlled setting like a lab. It includes details such as detection limits, accuracy, precision, calibration requirements, and QA/QC procedures. Those pieces of information are what let you determine whether the XRF can reliably quantify lead in soil samples, how to prepare samples, what measurement times to use, and what standards and blanks are needed to produce defensible results. In other words, the PCS is about enabling a laboratory-style lead analysis of soil samples, with appropriate data quality controls, rather than a general safety check or an airborne environmental assessment.
