Preferred Label : peak elution volume (time);
Detailed label : peak elution volume (time) in column chromatography, V R, t R;
IUPAC definition : The volume of mobile phase entering the column between the start of the elution and
the emergence of the peak maximum, or the corresponding time. In most of the cases,
this is equal to the total retention volume (time). There are, however, cases when
the elution process does not start immediately at sample introduction. For example,
in liquid chromatography, sometimes the column is washed with a liquid after the application
of the sample to displace certain components which are of no interest and during this
treatment the sample does not move along the column. In gas chromatography, there
are also cases when a liquid sample is applied to the top of the column but its elution
starts only after a given period. This term is useful in such cases.;
