Yahoo Answers like in a store not online and whats the difference between real chromatography paper and coffe filters? Before the flowing solvent reaches the farther edge of the paper, both solvents are evaporated, and the location of the separated components is identified, usually by application of reagents that form coloured compounds with the separated substances.
New types of chromatography developed during the s and s made the technique useful for many separation processes.
The strip should not touch the bottom of the cup.
If using alcohol or nail polish remover as all or part of your solvent, place a cap of aluminum foil over the glass to keep the vapours in the glass.

Size-exclusion chromatography Size-exclusion chromatography SEC is also known as gel permeation chromatography GPC or gel filtration chromatography and separates molecules according to their size or more accurately according to their hydrodynamic diameter or hydrodynamic volume.
It is very specific, but not very robust. Sensitive to all components, but not very sensitive to any. Two way chromatography has completely separated out the mixture into four distinct spots.
Operating parameters are adjusted to maximize the effect of this difference. Speed of handle movement for 3 times may vary with each member causing variation in the readings of fat.
