Standard Guide for Determination of Various Elements by Direct Current Plasma Atomic Emission Spectrometry
SIGNIFICANCE AND USE
5.1 Analyses using DCP-AES require proper preparation of test solutions, accurate calibration, and control of analytical procedures. ASTM test methods that refer to this guide shall provide specifics on test solutions, calibration, and procedures.
5.2 DCP-AES analysis is primarily concerned with testing materials for compliance with specifications, but may range from qualitative estimations to umpire analysis. These may involve measuring major and minor constituents or trace impurities, or both. This guide suggests some approaches to these different analytical needs.
5.3 This guide assists analysts in developing new methods.
5.4 It is assumed that the users of this guide will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that the work will be performed in a properly equipped laboratory.
5.5 This guide does not purport to define all of the quality assurance parameters necessary for DCP-AES analysis. Analysts should ensure that proper quality assurance procedures are followed, especially those defined by the test method. Refer to Guide E882.
SCOPE
1.1 This guide covers procedures for using a Direct Current Plasma Atomic Emission Spectrometer (DCP-AES) to determine the concentration of elements in solution. Recommendations are provided for preparing and calibrating the instrument, assessing instrument performance, diagnosing and correcting for interferences, measuring test solutions, and calculating results. A method to correct for instrument drift is included.
1.2 This guide does not specify all the operating conditions for a DCP-AES because of the differences between models of these instruments. Analysts should follow instructions provided by the manufacturer of the particular instrument.
1.3 This guide does not attempt to specify in detail all of the hardware components and computer software of the instrument. It is assumed that the instrument, whether commercially available, modified, or custom built, will be capable of performing the analyses for which it is intended, and that the analyst has verified this before performing the analysis.
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 and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 7.
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.
