A fraction in chemistry is a quantity collected from a batch of a substance in a fractionating separation process. In such a process, a mixture is separated
In chemistry and fluid mechanics, the volume fraction φ i {\displaystyle \varphi _{i}} is defined as the volume of a constituent Vi divided by the volume
In chemistry, the mass concentration ρi (or γi) is defined as the mass of a constituent mi divided by the volume of the mixture V. ρ i = m i V {\displaystyle
solubility at a given temperature. In cell fractionation, cell components are separated by difference in mass. A typical protocol to isolate a pure chemical
