Detection:

There are various ways one could detect the samples after capillary electrophoresis.  Instances are absorbance methods, fluorescence methods, mass spectrometry, conductivity measurements, amperometry, potentiometry, radiometry, electrochemical detection, etc.

Capillary Zone Electrophoresis:

Capillary Zone Electrophoresis also known as Free-Solution Capillary

Electrophoresis (FSCE) is the easiest form of Capillary Electrophoresis. It could be used to separate ionic species through their charge and frictional forces. The separation mechanism is based on differences within the charge-to-mass ratio of the analytes. Within traditional electrophoresis, electrically charged analytes move in a conductive liquid medium under the influence of an electric field.  Fundamental to CZE are homogeneity of the buffer solution and constant field strength throughout the length of the capillary. Introduced in the 1960s, the methods of capillary electrophoresis (CE) are designed to separate species based on their size to charge ratio in the interior of a small capillary filled along with an electrolyte. This method is used for the separation of small ions as well as for the separation of molecular species. Subsequent are the applications of this technique.
