What is a daily drift check and why is it important?

A daily drift check is a quick QA step that uses a stable, known standard to verify the XRF instrument’s response is stable from day to day. By running a short measurement on this reference material, you confirm that the tube voltage, detector gain, and other electronics haven’t drifted since the last check. If the signal stays within the established tolerance, you can trust that the instrument will produce consistent results for real samples for that day. This check is important because even small drift in the XRF system can shift intensities and energy calibration, leading to biased or inaccurate element concentrations. Detecting and addressing drift early maintains accuracy, precision, and compliance with QA requirements.
