Solvent vs. Eluent — What's the Difference?
Edited by Tayyaba Rehman — By Maham Liaqat — Updated on April 24, 2024
Solvent refers to any substance capable of dissolving another to form a solution, commonly used in various chemical processes, whereas eluent is specifically the liquid used in chromatography to carry the material to be separated.

Key Differences
Solvent is a general term for any substance, usually a liquid, that can dissolve another substance, resulting in a solution. It is widely used across chemistry for various processes like cleaning, extraction, and chemical reactions. On the other hand, eluent, a term specific to chromatography, is the liquid or gas that carries the substances through the chromatograph for separation.
While solvents are involved in creating solutions in a broad range of chemical applications, from industrial solvents removing greases to solvents in pharmaceuticals aiding drug delivery, eluents play a crucial role in the analytical process of separating mixtures into their individual components. The choice of eluent is critical for the effectiveness of the chromatographic separation.
Solvents can be organic, such as ethanol and acetone, or inorganic, such as water. These substances are chosen based on their ability to dissolve various solutes. Conversely, eluents are selected based on their ability to interact with the components of the mixture and the stationary phase of the chromatography setup, optimizing the separation process.
In terms of functionality, while all eluents are solvents in the context of chromatography, not all solvents are used as eluents. Solvents may serve in a wide variety of capacities beyond carrying substances for separation, such as in chemical synthesis and materials processing, whereas eluents are specifically used to control the separation of components in chromatographic systems.
The term solvent is more familiar and broadly applicable in everyday contexts, such as in household products or industrial applications, highlighting its versatility. In contrast, the term eluent is specialized and primarily used in scientific contexts, particularly in labs and research involving chromatographic techniques.
