This practice deals primarily with identifying the terms and relationships of those techniques that use ion exchange chromatography to separate mixtures and a conductivity detector to detect the separated components. However, most of the terms should also apply to ion chromatographic techniques that employ other separation and detection mechanisms. The apparatus to be used in the chromatography shall consist of syringe pumps, reciprocating pumps, pneumatic pumps, septum injectors, valve injectors, precolumns, concentrator columns, guard columns, separating columns, suppressor columns, conductivity suppressors, membrane suppressors, micromembrane suppressor, bulk property detectors, and solute property detectors. Chemical reagents to be used in the chemical analysis shall be of four kinds: mobile phase, stationary phase, solid support, and column packing materials. The stationary phase has two types which are the liquid phase and interactive solid phase material. Totally porous packing and pellicular packing are the two types of column packing materials.

1.1 This practice deals primarily with identifying the terms and relationships of those techniques that use ion exchange chromatography to separate mixtures and a conductivity detector to detect the separated components. However, most of the terms should also apply to ion chromatographic techniques that employ other separation and detection mechanisms. 1.2 Because ion chromatography is a liquid chromatographic technique, this practice uses, whenever possible the terms and relationships identified in Practice E682. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
