Types of Chemical markers

Capillary Electrophoresis Apparatus
It is conducted in a buffer filled, narrow-bore fused
silica capillaries.
Each capillary is about 25-100 μm inner diameter,
about 375 um outer diameter and 25-100 cm long,
and coated with external layer of polyimide for
protection.
Both extremities of the capillary tube rest in vials
filled with a buffer solution.
Some instruments include a temperature control
device to ensure reproducible results. This is
