Preparing your own thin layer chromatography plates (and then using them)

Step 8 Construct the developing chamber

The developing chamber is just a fancy name for a jar with a piece of filter paper in it. A 1cm layer of solvent (eluent) will be put in the bottom, the plate propped up inside, and the lid placed over. The point of the filter paper and lid is to ensure the atmosphere inside the chamber is well saturated with eluent.

First take a piece of filter paper and cut it such that there is one straight edge. When rolled and put inside the mason jar it should fit snugly along the wall of the jar.

That is it, the developing chamber is complete.
