A wide range of stationary phases, mobile phases and operating conditions have been employed in TLE. The layer is frequently 50-200 |im thick on a backing material of glass or organic polymer. Aluminium-backed plates are not suitable for use in TLE because of their electrical conductivity. TLE has been carried out on all thin layer adsorbants used for TLC, with silica, microcrystalline cellulose and alumina attracting the greatest interest.

Plates are generally 10-20 cm long and 5-20 cm wide. Longer plates tend to suffer from evaporative flow more than short ones and are generally avoided. The width of the plate is limited only by the current that the power supply is able to deliver at the required potential.
