Capillary electrophoresis separates charged molecules using an electric field within a capillary. It has several modes for diverse applications.

Capillary gel electrophoresis uses a porous gel polymer matrix to separate analytes based on size, making it useful for analyzing biomolecules like DNA and proteins.

In capillary zone electrophoresis, separation occurs based on differences in electrophoretic mobility.

It efficiently separates charged species like inorganic ions, organic acids, amines, and large biomolecules like proteins.

Micellar electrokinetic capillary chromatography separates neutral species based on their partitioning ability into a charged micelle, an aggregation of molecules with ionic heads and hydrophobic tails.

Capillary electrochromatography uses nonpolar stationary phase-packed capillary tubing, allowing neutral species separation through partitioning between the stationary phase and buffer solution.

Capillary isotachophoresis separates cations or anions with analyte bands migrating at the same velocity.

Capillary isoelectric focusing separates amphiprotic species that donate and accept protons using pH gradient buffer mixtures.
