Nomenclature for Chromatography

(IUPAC Recommmendations 1993)

This publication up-dated and revised the Nomenclature for Chromatography which was published in 1974. Since then there has been considerable development in gas chromatography with the widespread introduction of capillary columns, almost the entire development of high-performance liquid chromatography in its many forms and the introduction of specialised techniques such as coupled chromatography, supercritical fluid and ion chromatography. The Nomenclature covers primarily gas and liquid chromatography and both planar and column systems.

It contains sections on :

  1. General terminology
  2. Terms related to the chromatographic system
  3. Terms related to the chromatographic process and the theory of chromatography
  4. Terms related to detection
  5. Special terminology used in ion-exchange chromatography
  6. Special terminology used in exclusion chromatography and extensive indexes of terms and symbols

Noticeable changes from previous practice include the use of retention factor k instead of capacity factor k'. The use of N for efficiency, H for plate height and h for reduced plate height have standardised a confused area. These recommendations have now been adopted by the majority of journals publishing papers on chromatography.

Summary descriptions have appeared in a number of Journals including LC-GC and Chromatographia and the full paper has been translated into a number of languages, including most recently Polish.
