|Chlorate||20 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.
