Teaching the basics of pharmaceutical analysis by thin-layer chromatography and high-performance thin-layer chromatography to undergraduate students-laboratory practicals

As part of the renewal of the pharmacy students' curriculum, we planned a 2-day program with 9 exercises in thin-layer chromatography to teach the basics of the technique. Written reports with proper presentation of results were required. Related Issues such as simple experimental design were integrated into the program. The results and difficulties in their interpretation are described from a teacher's point of view. As in real life, some exercises do not allow simple conclusions or complete solutions to a problem. The mostly positive feedback about the program suggests the program served its purpose well.
