Scope

1.1 These test methods cover the determination of trace ([mu]g/L) levels of fluoride, acetate, formate, chloride, phosphate, and sulfate in high purity water using ion chromatography in combination with sample preconcentration. Other anions, such as bromide, nitrite, nitrate, sulfite, and iodide can be determined by this method. However, since they are rarely present in significant concentrations in high purity water, they are not included in this test method. Two test methods are presented and their ranges of application, as determined by a collaborative study, are as follows:

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

1.3 The common practical range of Test Method A is as follows: chloride, 1 to 100 [mu]g/L, phosphate, 3 to 100 [mu]g/L, and sulfate, 2 to 100 [mu]g/L.

1.4 The common practical range of Test Method B is as follows: fluoride, 1 to 100 [mu]g/L, acetate, 10 to 200 [mu]g/L, and formate, 5 to 200 [mu]g/L.

1.5 The values stated in SI units are to be regarded as the 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.
