Standard Practice for Establishing and Controlling Spark Atomic Emission Spectrochemical Analytical Curves

Standard Practice for Establishing and Controlling Spark Atomic Emission Spectrochemical Analytical Curves
$ 50.00 In stock

Significance and Use

5.1 This practice is intended to provide fundamental direction for the calibration, drift correction, and periodic control of the analytical curves for spark atomic emission spectrometers.

5.2 It is assumed that this practice will be used by trained operators capable of performing the procedures described herein.


1.1 This practice provides direction for establishing and controlling spark atomic emission spectrochemical analytical curves. The generation of analytical curves and their control are considered as separate though interrelated operations. This practice is applicable to spark atomic emission spectrometers.

Note 1: X-ray fluorescence spectrometric applications are no longer covered by this practice. See Guides E1361 and E1621 for discussion of this technique.

1.1.1 Since software programs are readily available to compute multiple linear regressions that can be used to generate analytical curves and since most instruments include this feature, this practice does not address this procedure. However, some recommendations are given to evaluate the equations that are generated.

1.2 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.

1.3 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.
