It was a technique to separate substances that had different colors. Basically, a chromatography is any lab technique in which we separate different chemical components of a mixture by their affinity to a stationary phase (usually silica gel in TLC) and to a mobile phase (the solvent or mixture of solvents). They don't necessary have to …
2) Silica Sand (Approx. 30%) Now, I have the silica sand to act like a river basin, but the black gravel always finds a way to get on to it. I need to know how to keep the gravel off the sand and keep the sand looking good, also I need to know how to separate them after they have mixed.
