ASTM D2791-07
Historical Standard: ASTM D2791-07 Standard Test Method for On-line Determination of Sodium in Water
SUPERSEDED (see Active link, below)
ASTM D2791
1. Scope
1.1 This test method covers the on-line determination of trace amounts of sodium in water using an ion-selective electrode.
1.2 This test method is based on on-line application of the sodium ion electrode as reported in the technical literature () . It is generally applicable over the range of 0.01 to 10 000 g/L.
1.3 The analyst should be aware that adequate collaborative data for precision and bias statements as required by Practice D 2777 are not provided. See Section for details.
1.4 The values stated in SI units are to be regarded as standard. The inch-pound units given in parentheses are for information only.
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. For specific hazard statements see Section 6.
