Extract

Increasing demands are being placed on the supervisors and operators of laboratories using XRF to establish the capability of their instruments in order to comply with internal requests and to meet customer quality assurance requirements through an audit procedure. To quantify just how accurate or precise the instrumentation is, a baseline must first be established on the instrument capability. Once the capability is documented, the precision of the instrument can be established and detection limits can be calculated. Establishing the capability of the instrument can provide a basis for developing a quality assurance procedure.
