paper chromatography is an analytical method used to seperate coloured chemicals or substances into individual compounds

Partition chromatography is method of separation in which the components present in the mixture get distributed more likely into two liquid phases because of differences in partition coefficients.

The partition coefficient (P) is defined as a particular ratio of the concentrations of a solute between the two solvents (a biphase of liquid phases), specifically for un-ionized solutes.When one of the solvents is water(polar solvent) and the other is a non-polar solvent.

HPLC PDA Detector. Diode array detectors(also referred to as a DAD detector or more specifically HPLC PDA detector) are used for obtaining spectral profiles from molecular mixtures or chromatographically separated samples.

Permeation(also called imbuing) is the penetration of permeate(such as liquid gas or vapour) through a solid.

Planar chromatography is one type of chromatography technique in which the stationary phase is on a flat plate and the mobile phase moves through stationary phase due to capillary action. This technique was used to separate the mixture. 

The plate model supposes that the chromatographic column is contains a large number of separate layers, called theoretical plates. Separate equilibrations of the sample between the stationary and mobile phase occur in these "plates".

the dipole moment and hydrogen bonding of a solvent determines type of compounds , it is able to dissolve and with other solvents or liquid compounds it is miscible.
