Thin Layer Chromatography Introduction Thin Layer Chromatography or TLC is a technique used as a separation and identification technique. There are many forms of chromatography‚ but one thing that remains constant throughout all of the types of chromatography is that there is a stationary phase and a mobile phase. In the case of TLC the stationary phase is the silica gel on the TLC tray. Procedure Chromatograph method is a method of separating mixtures of two or more compounds. Two phases

The materials used for this lab were filter papers‚ a choice chamber‚ eight pill bugs‚ water‚ and tin foil. The first step of the process is to trace and cut the filter paper so it fits neatly within each side of the choice chamber. Then‚ put water each filter paper and place the damp filter paper into the choice chamber. The damped filter paper causes the pill bugs to not be able to crawl under the paper and therefore disrupting the results. Four pill bugs should be placed on either side and one

absorption spectra it is possible to identify which peak correlates with which compound. Figure 2 contains a peak at around 500 and 700 nm which is a good indicator that that would-be chlorophyll b. This makes sense because this was the bottom band from the thin layer chromatography and chlorophyll b is the most polar compound. Chlorophyll B contains an aldehyde where chlorophyll A has a methyl group making it slightly more polar. Following that‚ figure 4 contains
