1.1 This multi-test method covers the determination of the oxyhalideschlorite, bromate, and chlorate, and bromide, in raw water, finished drinking water and bottled (non-carbonated) water by chemically and electrolytically suppressed ion chromatography. The ranges tested using this method for each analyte were as follows:

RangeSections
Test Method A:
Chemically Suppressed Ion Chromatography
8 to 19
Chlorite5 to 500 µg/L
Bromate1 to 25 µg/L
Bromide5 to 250 µg/L
Chlorate5 to 500 µg/L
Test Method B:
Electrolytically Suppressed Ion Chromatography
20 to 30
Chlorite20 to 1000 µg/L
Bromate1 to 30 µg/L
Bromide20 to 200 µg/L
Chlorate20 to 1000 µg/L

1.1.1 The upper limits may be extended by appropriate sample dilution or by the use of a smaller injection volume. Other ions of interest, such as fluoride, chloride, nitrite, nitrate, phosphate, and sulfate may also be determined using this method. However, analysis of these ions is not the object of this test method.

1.2 It is the user's responsibility to ensure the validity of these test methods for waters of untested matrices.

1.3 This test method is technically equivalent with Part B of U.S. EPA Method 300.1 , titled The Determination of Inorganic Anions in Drinking Water by Ion Chromatography.

1.4 The values stated in either SI or inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

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.
