A TLC-MALDI-TOFMS system has been developed for rapid identification of compounds in a mixture produced in an organic synthetic reaction. In this method, only main compounds were only identified. In the present work, some modifications were added to the TLC-MALDI-TOFMS system in order to detect minor components existing in the mixture at a much lower level. Detection limits attained by this modified system were comparable with that of a conventional MALDI-TOFMS system.
