Study Notes

Overview of Chromatography

A physical separation method that sorts components between two phases: stationary and mobile.
The mobile phase travels through the stationary phase in a specific direction, facilitating separation.
The process relies on the distribution constant differences of individual sample components.

Mechanism of Action

Chromatography allows molecules in a mixture to partition between stationary and mobile mediums.
Molecules that predominantly remain in the mobile phase are carried along more rapidly than those adhering to the stationary phase.

Applications

Widely used to separate and identify various components in complex mixtures, making it essential in chemistry and biochemistry.

Description

Explore the fundamental principles of chromatography, a physical separation method that differentiates components based on their distribution between two phases. This quiz covers how the mobile phase interacts with the stationary phase and the implications on sample component analysis.
