Historical Standard: ASTM D4519-94(2005) Standard Test Method for On-Line Determination of Anions and Carbon Dioxide in High Purity Water by Cation Exchange and Degassed Cation Conductivity
SUPERSEDED (see Active link, below)
ASTM D4519
1. Scope
1.1 This on-line test method includes hydrogen exchange and degassing by boiling and provides means for determining anions (such as Cl , SO 4 , NO 3 , and F ) at levels as low as 2 g/L (2 ppb) and carbon dioxide at the level of 0.01 to 10 mg/L (ppm) at 25C 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 SO 4 ), reference to and or provides the chloride or sulfate and CO 2 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 25C.
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.
