Formation of the extra (beta) carrier and displacer fronts were found to depend on the mobile phase flow rate. Classical displacement TLC was also performed to compare differences in the separation patterns obtained by TLC in both open (classical) and closed (forced-flow) systems. Two-dimensional (elution - displacement) TLC was also performed using forced flow. EP - 486 ER -
