Emission Spectroscopy1

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 the last revision. A number in parentheses indicates the year of the last reapproval. A
superscript epsilon (e) 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, seawater, 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.

1.4 This test method is not applicable to brines unless the
sample matrix can be matched or the sample can be diluted by
a factor of 200 up to 500 and still maintain the analyte
concentration above the detection limit.

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 and health practices and determine the applicability of regulatory limitations prior to use.
