Void Volume
where:
d = diameter of column [cm]
π = constant, ratio of circumference to diameter of a circle
l = length of column [cm]
f = fraction of column volume that is not taken up by stationary phase but
available for mobile phase; default value for f = 0.68 (for Hypersil)
Retention Time of Unretained Compound t (m) [min]
(Also referred to as dead time or void time)
where:
F = flow rate of LC [ml/min]
