The common way the scientific knowledge is discovered passes through several steps:
First you observe the phenomenon around you. Then you develop a certain hypothesis based on your observation. After that you start testing your hypothesis and collecting the resultant data from your tests.
Finally comes the conclusion of whether your hypothesis is accepted or rejected.
If it is accepted, it can further develop into a theory and a publication afterwards.
The answer is: hypothesis
Using a thin stationary phase supported by an inert backing, thin layer chromatography (TLC) is a chromatographic technique used to separate the components of a mixture.
It can be carried out on an analytical scale to track the development of a reaction or on a preparative scale to purify minute quantities of a chemical. Because of its simplicity, comparatively low cost, great sensitivity, and rapid separation, TLC is an extensively used analytical method. Similar to all chromatography, TLC works on the premise that a chemical will have varying affinities for the mobile and stationary phases, which will influence how quickly it migrates. TLC aims to produce well-defined, well-separated spots.
