Batch or Pre-Column Chromatography methods are generally fast, easy, have high recovery (amt. of PoI want to keep vs. amt. of contaminants want to get rid of in a given number of samples) and have low resolution (purification factor of total protein).
Column Chromatography Methods require a more extensive process, but generally have higher resolution than Batch Chromatography methods.
Hope this helped :)
Well, this way you will know what different substances are present in a mixture in a relatively simple way. It is also rather effective, as long as the mixture is actually soluble in the liquid.
is that it can usually be scaled to the project at hand. This is especially useful if one is trying to separate .. By amanjot kaur ..
assignment mo kay RDB to hahaha taga UE ka :p
ibg sbhn taga UE ka rin.. alam mo ung tanong.
sipag ng RED WARRIORS huh ! :] GO UE WARRIORS , GO FIGHT, FIGHT, FIGHT :]
con-- solvent usage high
The name Chromatography comes from the greek word "Chromos" meaning color and "grafein" meaning to write. So, Chromatography is "writing with colors"...
yer no
By filtering
Analytically GLC is the best (Gas chromatography)In a productive way distillation is prominent.
Thin layer chromatography can be used to identify a compound because for certain reaction mixtures, TLC can separate all compounds in a mixture based on the distance the compound travels on the TLC film. With the proper solvent system, TLC can be used to uniquely identify a compound.
Chromatography is a way to separate mixtures. You start by dissolving your sample in a mobile phase. This mobile phase travels through a structure, the stationary phase. Depending on how much the compounds in the mixture like or dislike the stationary phase they will move at different speeds throughout the stationary phase. This allows for slower moving compounds to separate from fast moving compounds and allowing you to collect different compounds from a single mixture.

Lets say you have mixture of sand and salt. Put your mixture on a filter paper and by using a strong magnet you should be able to separate sand from salt. Using a magnet is a powerful way to separate out one solid from another in a mixture.
i think the definition of chromatography is the showing of colors in a different color. In other words it is the separation of a mixture showing what colors are in that mixture. by the way, check out the question that asks how many popsicles are in the world. its really cool! well the answer is. :-)
There is a easy way. Just bubble it in water.

Any form of chromatography could be used to separate liquid ink.Thin Layer Chromatography would be the simplest method:-Put a dot of the black ink around 1/4 of the way up a piece of filter paper.Place the filter paper in a buffer solution (usually a mixture of methanol and cyclohexane), but don't submerge the dot of ink.Wait for the buffer solution to get most of the way up the filter paper via absorptionThe black ink should have separated into several different colours that have moved different distances up the filter paper.
Column chromatography is used in the lab and industry to isolate the compound that they want. Since some chemical reactions are not selective to the product you want, you have to get rid of the products you don't want. Sometimes column chromatography is the only way.
Yes, a magnet is one way that can be used to separate a mixture of iron filings and sulfur.
