| Significance and Use | ||||||||||||||||||||
|
5.1 Small quantities of sodium, 1 to 10 μg/L, can be significant in high pressure boiler systems and in nuclear power systems. Steam condensate from such systems must have less than 10 μg/L. In addition, condensate polishing system effluents should have less than 1 μg/L. Graphite furnace atomic absorption spectroscopy (GFAAS) represents technique for determining low concentrations of sodium. |

| 1. Scope | ||||||||||||||||||||
|
1.1 This test method covers the determination of trace sodium in high purity water. The method range of concentration is 1 to 40 μg/L sodium. The analyst may extend the range once its applicability has been ascertained. 1.2 This test method is a graphite
furnace atomic absorption spectrophotometric method for the
determination of trace sodium impurities in ultra high purity
water.
1.3 This test method has been used successfully with a high purity water matrix.2 It is the responsibility of the analyst to determine the suitability of the test method for other matrices. 1.4 The values stated in SI units are to be regarded as standard. 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. |
