This test method can be a useful diagnostic tool in measuring the impurities and detecting their sources in high purity water, the steam condensate of high pressure power plants, and in the... View More

scope:

1.1 This on-line test method includes hydrogen exchange and degassing by boiling and provides means for determining anions (such as Cl , SO4−−, NO 3, and F ) at levels as low as 2 μg/L (2 ppb) and carbon dioxide at the level of 0.01 to 10 mg/L (ppm) at 25°C in high purity water and steam condensate by measuring electrical conductivity.

1.2 The conductivity of all anions (except OH ) is determined and not the conductivity of an individual anion if more than one is present. If only one anion is present (such as Cl or SO4 −−), reference to Table 1 and Table 2 or Figs. 1-3 provides the chloride or sulfate and CO2 concentration.

1.3 This test method has been improved in accuracy by using a modern microprocessor instrument for conductivity and temperature measurement and appropriate temperature compensation algorithms for compensation to 25°C.

1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the 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.
