Standard Guide for Elemental Analysis by Wavelength Dispersive X-Ray Fluorescence Spectrometry

SIGNIFICANCE AND USE
5.1 X-ray fluorescence spectrometry can provide an accurate determination of metallic and many non-metallic elements in a wide variety of solid and liquid materials. This guide covers the information that should be included in an X-ray spectrometric analytical method and provides direction to the user for determining the optimum conditions needed to achieve acceptable accuracy.  
5.2 The accuracy of a determination is a function of the calibration algorithm, the sample preparation, and the sample homogeneity. Close attention to all aspects of these areas is necessary to achieve acceptable results.  
5.3 All concepts discussed in this guide are explored in detail in a number of published texts and in the scientific literature.
SCOPE
1.1 This standard provides guidelines for developing and describing analytical procedures using a wavelength dispersive X-ray spectrometer for elemental analysis of solid metals, ores, and related materials. Material forms discussed herein include solids, powders, and solid forms prepared by chemical and physical processes such as borate fusion and pressing of briquettes.  
1.2 Liquids are not discussed in this guide because they are much less frequently encountered in metals and mining laboratories. However, aqueous liquids can be processed by borate fusion to create solid specimens, and X-ray spectrometers can be equipped to handle liquids directly.  
1.3 Some provisions of this guide may be applicable to the use of an energy dispersive X-ray spectrometer.  
1.4 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Standard Guide for Validating Analytical Methods

SIGNIFICANCE AND USE
4.1 Method validation is a process of demonstrating that the method meets the required performance capabilities. International standards such as ISO/IEC 17025, certifying bodies, and regulatory agencies require evidence that analytical methods are capable of producing valid results. This applies to laboratories using published standard test methods, modified standard test methods, and in-house test methods.  
4.2 Although a collaborative study is part of this guide, this guide may be used by a single laboratory for method validation when a formal collaboration study is not practical. This guide may also be applied before a full collaboration study to predict the reliability of the method.  
4.3 The use of multiple validation techniques described in this guide increases confidence in the validity or application of the method.  
4.4 It is beyond the scope of this guide to describe fully the fundamental considerations in Section 5. For a more descriptive definition of these concepts, refer to the International Union of Pure and Applied Chemistry (IUPAC) technical report, “Harmonized Guidelines for Single Laboratory Validation of Methods of Analysis” (1), the IUPAC Compendium of Analytical Nomenclature (Orange Book) (2), and the Eurachem publication, The Fitness for Purpose of Analytical Methods, A Laboratory Guide to Method Validation and Related Topics (3).
SCOPE
1.1 This guide describes procedures for the validation of chemical and spectrochemical analytical test methods that are used by a metals, ores, and related materials analysis laboratory.  
1.2 This guide may be applied to the validation of laboratory developed (in-house) methods, addition of analytes to an existing standard test method, variation or scope expansion of an existing standard method, or the use of new or different laboratory equipment.  
1.3 The suggested approaches in this guide may also be used to validate the implementation of standard test methods used routinely by laboratories of the mining, ore processing, and metals industry.  
1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

1.2 This test method has been interlaboratory tested for the elements and ranges specified in the quantitative range part of the table in 1.1. It may be possible to extend this test method to other elements or broader mass fraction ranges as shown in the application range part of the table above provided that test method validation is performed that includes evaluation of method sensitivity, precision, and bias. Additionally, the validation study shall evaluate the acceptability of sample preparation methodology using reference materials or spike recoveries, or both. Guide E2857 provides information on validation of analytical methods for alloy analysis.  
1.3 Because of the lack of certified reference materials (CRMs) containing bismuth, hafnium, and magnesium, these elements were not included in the scope or the interlaboratory study (ILS). It may be possible to extend the scope of this test method to include these elements provided that method validation includes the evaluation of method sensitivity, precision, and bias during the development of the testing method.  
1.4 Units—The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use.
