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

Lab #3: Ion Exchange Chromatography Objective The purpose of this experiment was to separate proteins on the basis of their net charge at a particular pH. In cation exchange chromatography positively charged molecules are attracted to a negatively charged column. Conversely‚ in anion exchange chromatography‚ negatively charged molecules are attracted to a positively charged column. Experimental results could be monitored in a predictable way by controlling running pH‚ salt concentration‚ and by

Solubility as a Property of Matter A Lab of Chemicals‚ Chromatography‚ and Crime! Chemistry is a natural science that deals with the composition of matter and the changes it undergoes. At crime scenes‚ investigators often find unknown materials that need to be identified. If an unknown material is a mixture‚ an investigator may want to know one or two things about it: What are the ingredients of the mixture? Is the mixture found at the scene the same as a known mixture? A mixture is a collection
