This is the BEST explanation of how chromatography works. It completely boggles my mind that I'm paying to sit in lectures and be "taught" lab techniques by professors who explain absolutely nothing about how this works when the explanation is so simple. Thank you!

Thanks, Daniel. Please share with your colleagues, friends and students. I am always working on new videos to add to my channel at kzfaq.info

Very useful video Sir..would be of great help if you could kindly make one on HPLC and other Chromatography techniques..!!!

So a man with the surname Tsvet (which means 'colour' in Russian) invents a chromatography (which means 'colour'+'to write' in Greek). What a wonderful coincidence!

Hi, in paper chromatography, the stationary phase consists of water molecules embedded within the porous structure of the cellulose fibers. Thus, this stationary phase is polar in nature. However, the solvent used normally in separation of say a black ink typically involves the use of water as a solvent which is polar also. Thus, wouldn't the interaction between the solvent (water) and the stationary phase (polar) make the water molecules in the solvent be adsorbed more strongly onto the stationary phase? I'm confused as to how the water is able to travel up the chromatography paper when its interaction with the stationary phase is strong.

Hi Heider. during both paper and thin-layer chromatography, solvents migrate up the stationary phase through a phenomenon akin to capillary action (the same reason you see a convex meniscus when water is placed in a narrow cylinder). Solvent molecules have an attraction to both the paper and other solvent molecules, so they 'drag' one another along as they move upward, seeking out new stationary phase to interact with.
