Each features many depressions (or wells), either 12 or 24, in … WebUsing a pencil, draw a line across the plate at the 0.5 cm mark. This is the origin: the line on which you will spot the plate. Take care not to press so hard with the pencil that you disturb the adsorbent. Under the line, mark lightly the name of the samples you will spot on the plate, or mark numbers for time points. WebThen take your micropipet and lightly touch the TLC plate at the labeled point for that chemical (Fig 2.2). The liquid inside the TLC will move to the plate, forming a spot. Make sure not to put too much material on the plate. A good size for the spot is around 1-2 mm. Then apply the chemical to the cospot in the same way as the previous step. infry
