Operational Protocols

Transmission of a mixture of pigments through a layer of colorless sorbent and registration of colored areas of chromagrams. Two labeled sealed experimental chambers are used in the experiment. Each chamber contains a sheet of chromatographic paper and a syringe filled with a chlorophyll solution. Chlorophyll is produced from leaves of a Brazilian plant and dissolved in ethyl alcohol. The chlorophyll chromatography activation is performed through solution injection to the chromatographic paper. As molecules in chlorophyll pigments have different characteristics (such as size and dissolubility), they move with different velocities over the paper sheet under the effect of solvent (ethylene glycol in this case). Chlorophyll has different pigments (carotenes, xanthophylls, chlorophyll A and chlorophyll B) of a typical color. When chlorophyll solution passes through chromatographic paper, molecules of each of pigments behave differently, that results in a phenomenon similar to a rainbow. As the gravity influences the capillary effect, different chromatograms will be received in zero-g conditions and on the ground. To register the chlorophyll chromatography process, photography performed by onboard aids of the Russian segment is used.
