ASTM D4190-08

This document is not anASTM standard and is intended only to provide the user of anASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

Standard Test Method for
Elements in Water by Direct-Current Plasma Atomic
1
Emission Spectroscopy
This standard is issued under the fixed designation D 4190; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
1. Scope *
1.1 This test method covers the determination of dissolved and total recoverable elements in water, which includes drinking
water, lake water, river water, sea water, snow, and Type II reagent water by direct current plasma atomic emission spectroscopy
(DCP).
1.2 The information on precision and bias may not apply to other waters.
1.3 This test method is applicable to the 15 elements listed in Annex A1 (Table A1.1) and covers the ranges in Table 1.

of 200 up to 500 and still maintain the analyte concentration above the detection limit.
1.5
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6 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.

4. Summary of Test Method
4.1Elements are determined, either sequentially or simultaneously, by d-c plasma atomic emission spectroscopy.
4.1 Elements are determined, either sequentially or simultaneously, by DCP.
4.2 Matrix enhancement or suppression of the emission signal can be minimized by the addition of 2000 mg/L of lithium ion
to all standards, samples, and blanks.
