La cellulose du papier très hydrophile phase fixe. La phase mobile migre par capillarité WebThe use of a hydrophobic stationary phase is essentially the reverse of normal phase chromatography, since the polarity of the mobile and stationary phases have been inverted – hence the term reversed-phase chromatography. [2] [3] Reversed-phase chromatography employs a polar ( aqueous) mobile phase.

La phase … A hydrophile is a molecule or other molecular entity that is attracted to water molecules and tends to be dissolved by water. In contrast, hydrophobes are not attracted to water and may seem to be repelled by it. Hygroscopics are attracted to water, but are not dissolved by water.
