What best describes the difference between calibration and quality control?

Calibration sets how the instrument responds to known standards, establishing the link between the instrument signal and the true value. Quality control then monitors performance over time using control materials with known values to verify that results remain accurate and precise in routine testing. Together, these describe both the setup step that aligns measurements to true values and the ongoing check that detects drift or issues during daily operation. Calibration does not replace quality control; both are necessary to ensure reliable results.
