Gel filtration or gel permeation is a process by which molecules can be separated according to their size(molecular weight) and sometimes shape. small molecules get trapped and slowed down in the pores of the beads but large molecules simply flow down the column..therefore larger molecules come out first.
Gel permeation chromatography (GPC) is a type of size exclusion chromatography that separates molecules based on their size. In GPC, a sample is dissolved in a mobile phase and passed through a column filled with porous beads. Smaller molecules enter the pores and take longer to elute, while larger molecules pass through more quickly. The molecules are detected as they elute from the column, typically using a UV or refractive index detector.

What is included volume in gel chromatography?
In gel chromatography, the included volume refers to the volume of the gel column through which a solute can pass without being significantly retarded. It is the volume of the gel matrix accessible to the solute molecules for separation. The included volume influences the resolution and efficiency of the chromatographic separation.
Why you use silica gel in chromatography?
Silica gel is commonly used in chromatography as a stationary phase due to its high surface area and ability to adsorb a wide range of compounds. It provides good separation of components based on their size, polarity, and interactions with the silica surface.
Separation of hemoglobin and riboflavin by gel chromatography?
Gel chromatography is a size exclusion technique that separates molecules based on their size. Hemoglobin, being a larger molecule, will elute earlier than riboflavin, which is smaller, in a gel chromatography column. By running a sample containing both compounds through the column, hemoglobin will be separated from riboflavin based on their molecular sizes, allowing for individual collection and analysis of each compound.
What is the column material in gel filtration chromatography?
The column material in gel filtration chromatography is typically composed of porous beads made from materials like agarose or dextran. These beads vary in size and create a porous network that separates molecules based on their size as they pass through the column.

What is absorbent in chromatography?
An absorbent in chromatography refers to the material used to support or hold the stationary phase in the chromatography. It serves to facilitate the separation of components in the sample as they flow through the stationary phase. Common absorbents include silica gel, alumina, and cellulose.
