Scope

1.1 This guide describes the components for a wavelength-dispersive X-ray fluorescence system for materials analysis. This guide can be used as a reference in the apparatus section of test methods for wavelength-dispersive X-ray fluorescence (WDXRF) analyses of nuclear materials.

1.2 The components recommended include X-ray detectors, signal processing electronics, excitation sources, and dispersing crystals.

1.3 Detailed data analysis procedures are not described or recommended, as they may be unique to a particular analysis problem. Some applications may require the use of complex computer software during data reduction to correct for matrix effects.

1.4 The values stated in SI units are to be regarded as the standard.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Significance and Use

This guide describes typical prospective analytical X-ray fluorescence systems that may be used for qualitative and quantitative elemental analyses of materials related to the nuclear fuel cycle.

Standard test methods for the determination of materials using wavelength-dispersive XRF⁴ usually employ apparatus with the components described in this guide.
