Dead volume is the total volume of the liquid phase in the chromatographic column. It is obvious from the definition that V o is the geometrical parameter, and it should not be dependent on the types of analytes and mobile phase. This definition is the most general and it is true if the stationary phase (adsorbent) used is rigid, nonsoluble and ...

Void ratio and porosity differ only in the denominator. Void ratio is the ratio of voids to solids, porosity is the ratio of voids to total volume.

Get PriceVolume/Solid or Space/Form; Mass/Void Interaction. When a void occurs, the space between two solids it is passive. When it occurs as a removal, or subtraction, from a solid, the void is active. Penetration of space can be regarded as empty space entering into a solid form. Penetration is a deep incursion of space into a mass, where as concavity ...

Get PriceIn soil mechanics, the void ratio describes the relationship between the volume of voids, or spaces, in the soil or aggregate to the volume of solid constituents, or grains. Algebraically, e = Vv /Vs, where e represents the void ratio, Vv represents the volume of voids and Vs represent the volume .

Get PriceMar 01, 2013 · In modeling solid-state structures, atoms and ions are most often modeled as spheres. A structure built using spheres will have some empty, or void, space in it. A measure of void space in a particular structure is the packing efficiency, defined as the volume occupied by the spheres divided by the total volume of the structure.

Void Volume. The void volume is the volume of mobile phase (V m or V 0) in a column. For example, if the stationary phase occupies 40% of the total column volume, the void volume would be 60% of the total column volume. Consider a column that is 25 cm long with an inner diameter of 1 cm.

Get PriceConcrete block, also known as a concrete masonry unit and sometimes called a cinder block, typically has one or two holes or voids to reduce the weight of the block. To estimate how much grout is needed to fill those voids you need to find the volume of each void and ply that by .

Get PricePorosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and . Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface (cf. closed-cell foam).
