Identification of Plant Pigments by Paper Chromatography Biology 1107L Introduction All living organisms require energy for their chemical processes. The ultimate source of this energy is the sun. Plants convert light energy into the chemical energy of sugars. During photosynthesis pigments are used to capture light energy. Pigments of green plants can easily be separated and identified using a technique called paper chromatography. The purpose of this experiment is to separate

CHROMOTOGRAPHY Chromatography is used to separate mixtures of substances into their components. All forms of chromatography work on the same principle that they all have a stationary phase (a solid or a liquid supported on a solid) and a mobile phase where liquid or a gas is involved. The mobile phase flows through the stationary phase and carries the components of the mixtures with it. Different components travel at different rates. In paper chromatography‚ the stationary phase is a very uniform

of our purer LDH sample that we were unable to collect and use. Another thing to note is that our values for the affinity chromatography step were almost the same as the amount for the size exclusion chromatography step. The total activity was 96.50U and the percent yield was 29.76% for the size exclusion. The lack of purity and low recovery of our size exclusion chromatography could be due to the column beads not being packed and settled before we ran our sample through it‚ since the column leaked

Gas Chromatography (GC) Definition: Gas chromatography is a physical method of separation in which the components to be separated are distributed between two phases‚ one being a stationary bed of large surface area‚ and the other a gas that percolates through the stationary bed. When the stationary phase is a solid‚ the separation process is more precisely called gas-solid chromatography. Introduction: Gas Chromatography is a technique widely used to separate complex mixtures of substances. Compounds
