Description of ASTM-D5542 2016ASTM D5542-16Active Standard: Standard Test Methods for Trace Anions in High Purity Water by Ion ChromatographyASTM D5542Scope 1.1 These test methods cover the determination of trace (μg/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:
(A) Limit of detection is lowest measurable concentration not reportable as zero at 99 % level of confidence as
per EPRI study as cited in Sections 16 and 24.
(B) Insufficient data to calculate limit of detection.
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 μg/L, phosphate, 3 to 100 μg/L, and sulfate, 2 to 100 μg/L. 1.4 The common practical range of Test Method B is as follows: fluoride, 1 to 100 μg/L, acetate, 10 to 200 μg/L, and formate, 5 to 200 μg/L. 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.
