Types of Gels

Generally, gels can be divided into elastic gels (reversible gels) and non-elastic gels (irreversible gels), which have different properties and therefore different applications as well as commercial values.

Colloids, Sol, and Gels

A colloid is a mixture in which one substance of dispersed insoluble particles is suspended throughout another substance. Sol and gels are two important types of colloids, and there are obvious differences between them.

Gel Filtration Chromatography

Gel filtration chromatography is a type of chromatography that separates components based on their molecular sizes using porous gel beads of a particular porosity. It is also used to assess the molecular weight of substances.
