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.
