phase ratio, \(\beta\)

in chromatography
https://doi.org/10.1351/goldbook.P04531
The ratio of the volume of the mobile phase to that of the stationary phase in a column: \[\beta = \frac{V_{0}}{V_{\text{s}}}\] In the case of open-tubular columns the geometric internal volume of the tube (\(V_{\text{c}}\)) is to be substituted for \(V_{0}\).
