Description

This simple, accurate,
and economical activity
clearly illustrates the
principles of thin-layer
chromatography to
beginning students in just one lab session. Students
use indicators, developers, and chromatography
chambers to run chromatograms of five different
dye solutions to learn about rate of flow, then run
chromatograms of two “unknown” solutions. You
can also use this to determine the purity of a system.
It contains enough materials for up 24 students, a
teacher’s manual, and student worksheets.
