Term: partition chromatography https://doi.org/10.1351/goldbook.P04436 Definition: chromatography in which separation is based mainly on differences between the solubility of the sample components in the stationary phase ( gas chromatography), or on differences between the solubilities of the components in the mobile and stationary phases (liquid chromatography).
