An automated system for carrying out the development of the thin-layer plate was assembled. The automated system consists of a conventional glass chamber, a mechanical unit for lifting the thin-layer plate and a double-beam optical sensor for detecting the solvent front. Development is stopped by lifting out the thin-layer plate from the glass chamber exactly after arrival of the solvent front at the pre-setted position monitored by the optical sensor. The reliable detection of the solvent front by the double-beam optical sensor offers reproducible results of development. By using this system, a laborious and time-consuming work in TLC can be significantly reduced.
