Ion Exchange Chromatography (IEC) is a pivotal technique for separating proteins and biomolecules based on charge. It utilizes a resin with charged groups to bind oppositely charged molecules, allowing for high specificity in purification processes. IEC is instrumental in pharmaceuticals for drug purification, in food safety, clinical diagnostics, environmental testing, and biomedical research. The method's precision in protein purification is particularly noteworthy, as it maintains the native structure and function of proteins.

Molecules with a charge opposite to that of the resin's functional groups are retained, while others pass through
\( K_{\text{ads}} \) is a measure of the affinity between the ions and the resin, with higher values indicating stronger binding and longer retention times
The strength of retention is modulated by the pH and ionic strength of the mobile phase, which can be adjusted to optimize separation
Uses a resin with positively charged groups to attract and bind negatively charged molecules
Uses a resin with negatively charged groups to capture positively charged species
Employed for the purification of drugs and the preparation of ultrapure water
Used to refine proteins and amino acids, contributing to food safety and quality
Aids in the analysis of biological fluids for diagnostic purposes
Utilized for assessing water and soil purity, monitoring contaminants such as heavy metals and nitrates
Crucial for understanding disease mechanisms and developing diagnostic assays through its precision in separating specific proteins
High resolution, specificity, and ability to scale up for industrial applications, as well as reproducibility and compatibility with a variety of sample types
Requires precise control of experimental conditions and can have issues with resin stability and nonspecific interactions
