void ratio

void ratio  

A measure of the porosity of rocks and soils; the void ratio (e) = Vv/Vs, where Vv is the volume of air in voids and Vs is the volume of solid particles.
bed volume

bed volume  

In column chromatography, the total volume of material, both solid and liquid, in the column; i.e. the volume of the support particles plus the void volume. It is synonymous with column volume for a ...
exclusion volume

exclusion volume  

The volume of solvent retained by the column bed in gel‐permeation chromatography that is outside the gel particles. Compare void volume.
blue dextran

blue dextran  

A soluble dextran, of average Mr 106, conjugated with the dye Reactive Blue 2. It is useful in gel filtration for checking column packing and determining the void volume.
Whitaker plot

Whitaker plot  

A plot that, ideally, gives a linear correlation between the logarithm of the relative molecular mass of a macromolecule and the ratio of the elution volume, V, to the void ...
space

space  

Reference type:
Overview Page
Pre-modernist architects and theorists used the term quite prosaically as a synonym for ‘volume’ or ‘void’. However, ‘space’ became a defining concept of most versions of Modernism by appropriating a ...
specific yield

specific yield  

1 The ratio of the water drained from a rock under the influence of gravity, or removed by pumping, to the total volume of the rock voids or pore space in the drained rock. The difference is caused ...
redshift survey

redshift survey

porosity

porosity  

Absolute porosity is the total of all void spaces present within a rock, but not all these spaces will be interconnected and thus able to contain and transmit fluids. The effective porosity is thus ...
