In column chromatography, the enzymes are made to pass through the column without occurrence of bubbles. These enzymes are obtained at the end of the process by slowly advancing through every column.

Why do the pigments separate during column chromatography?
Because the retention coefficients of different substances are also different.
What is the difference between flash chromatography and column chromatography?
Column chromatography, is a broad term for all column chromatography methods, but is also synonomous with Gravity fed methods. Flash chromotography refers specifically to a column in which the eluant (or mobile phase) is moved through the column under pressure (using a hand pump for small scale, or a pressurised gas for a larger scale), the name Flash is derived from how much faster it is to run a column under pressure than via gravity.
What is the name of the method used to separate dyes?
Chromatography is the method used to separate a mixture of dyes or inks.
Can chromatography be used to separate mixtures?
Chromatography is used in case of an investigation as in the analysis of poisoned food, chromatography can help find individual components.
What is the column material in gel filtration chromatography?
the column is some strange scientist

Why are the plates in column chromatography called 'theoretical plates'?
The number of theoretical plates in a chromatography column is a measure of how "long" the column is - how well it separates. A "short" column will only separate large or heavy molecules, and the medium and light stuff is still mixed together in the last band. A "long" column will separate the little stuff better because there are more theorectical plates. Picture a stack of sieves with smaller and smaller holes as the column gets "longer" and you've got the idea. This "length" has virtually nothing to do with the physical length of the separating column. It is a function of the packing materials and solvents used during a separation.

Where could chromatography be used?
Chromatography comprises a wide variety of analytical methods and is a common tool for chemists. Chromatography can be used in two main ways: preparatory work and analysis. In preparatory work, the chromatography column can be used to separate one type of molecule from another based on the characteristics of that molecule. An example would be taking the cellular components of digested cells and separating the DNA out from all of the other components. In analysis, an unknown sample can be sent through a chromatography column which is set up to an analyzer (for which there are many kinds). Molecules separate based on their characteristics and the detector can record how long it takes them to leave the column. Standards (solutions that have a known chemical in them) can be used for comparison. If a standard and an unknown compound both move through the same column in the same amount of time, it is reasonable to assume that this is what the unknown is. Chromatography is used in all forms of science and new methods and techniques have been created to enhance the detection limits and usefulness of chromatography. The details of chromatography are quite in depth as this is a complex kind of scientific analysis.
What is an elution buffer-Elution?
In column chromatography, it is put in the column to basically cleanse and lubricate. Generally, it helps to wash out any left-over proteins from a previous experiment. It can also help to separate the fractions that are collected.
What is the purpose of an alumina column?
Column chromatography is generally used as a purification technique: it isolates desired compounds from a mixture.Column chromatography is separated into two categories, depending on how the solvent flows down the column. If the solvent is allowed to flow down the column by gravity, or percolation, it is called gravity column chromatography. If the solvent is forced down the column by positive air pressure, it is called flash chromatography, a "state of the art" method currently used in organic chemistry research laboratories The term "flash chromatography" was coined by Professor W. Clark Still because it can be done in a "flash."
