Retention Parameters in Gas Chromatography

This paper presents a revision of terms in Chapter 3.6 THE MOBILE PHASE and Chapter 3.7 RETENTION PARAMETERS IN COLUMN CHROMATOGRAPHY of the NOMENCLATURE FOR CHROMATOGRAPHY {"Nomenclature for Chromatography (IUPAC Recommendations 1993)", Pure Appl. Chem., 65, 819-872 (1993)}, with the aims of (i) emphasizing the physical meaning of the terms and (ii) specifying the temperatures and pressures for the terms for gas volumes and flow rates. A number of the original terms were found to be misleading or superfluous, including such terms as corrected retention time, net retention time, total retention volume (time), specific retention volume at 0 C, relative pressure; and their usage is strongly discouraged. Chapter 1.1 BASIC DEFINITIONS was supplemented with the terms chromatographic system and chromatographic process.
