Capillary electrophoresis is an analytical technique that separates ions based on their electrophoretic mobility with the use of an applied voltage. ... Neutral species are not affected, only ions move with the electric field. If two ions are the same size, the one with greater charge will move the fastest.

Which method is used in capillary electrophoresis?

Capillary zone electrophoresis (CZE)

The capillary column is immersed into two buffer-filled reservoirs to which a high voltage is applied via platinum electrodes. The sample is stored in a separate reservoir and can be injected into the capillary by various techniques such as a hydrodynamic or electrokinetic impulse.

What is the use of capillary electrophoresis?

Capillary electrophoresis in industry is used to analyse products such as; food additives, herbicide, animal nutrition, and detergents. In particular, CZE is used to separate and identify the small molecules existing in these types of samples.
