Who is primarily responsible for calibrating an XRF analyzer?

The manufacturer is primarily responsible for calibrating an XRF (X-ray fluorescence) analyzer, as they hold the expertise and technical knowledge necessary to ensure the instrument is operating accurately and meeting all specified performance standards. Proper calibration is essential for accurate lead measurement and is often part of the quality control process implemented by manufacturers. They conduct rigorous evaluations and validations to align the equipment's performance with regulatory guidelines.

Users, such as inspectors, may perform routine calibrations or checks; however, these are typically less comprehensive than the original calibration provided by the manufacturer. Laboratory technicians may assist in the calibration process or operation of the equipment, but they generally follow the manufacturer's procedures and guidelines rather than independently calibrate the device. The responsibility ultimately lies with the manufacturer to provide a properly calibrated and functioning unit upon sale or distribution, thereby ensuring that the users of the equipment can rely on its measurements for compliance and safety assessments.
