Abstract

This paper describes the fundamental factors causing the 'disturbing zone' in OPLC. This phenomenon of distorted substance zones appears when the OPLC separation is started with a dry layer and is due to interaction between the gas that is physically bound to the surface of the sorbent (m//a) and the gas molecules dissolved in the eluent (m//s). Possibilities for elimination of the adverse effects of disturbing zones ultimately depend on the establishment of operating conditions that inhibit their initial formation. Since modification of the location of the disturbing zone is only possible within a very narrow range, the sole solution to this problem is to conduct a pre-run, which may be carried out with hexane in the case of separation of apolar compounds.
