there are several types of chromatography; all types employ a mobile phase or eluent (it can be liquid or gas), which is forced through a stationary phase (a solid or semi-solid). the mobile phase takes advantage of differing solubility or polarity of the components in order to separate them. a line drawn at the bottom edge of the paper is the starting line. this is the finish line. when the solvent front reaches the finish line, the paper should be removed immediately from contact with the mobile phase.
this can be confusing when interpreting the chromatogram. a component with a given solubility travels along with the mobile phase at one rate, regardless of what other components are present in the sample. comparing the rf values allows the confirmation of a component in multiple samples because unique components have unique r f values. be sure to handle only the dry part or the chromatogram when removing it from the beaker. for more information contact us at email@example.com or check out our status page at .org.

the ink chromatography method separates components that may not visible in the original ink sample.copyrightcopyright © 2004 natrij, wikimedia commons .org/wiki/file:tlc_black_ink.jpg a firm understanding of solutions and mixtures and their components is essential for environmental engineers whose challenge is to prepare solutions to monitor and test groundwater for contaminants, and to develop remediation processes that separate pollutants from their water solutions. analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred. it includes teacher instructions for a class demonstration that gives students the chance to compare and contrast the physical characteristics of some simple mixtures and solutions. in order to develop and apply methods of water remediation, environmental engineers, must also be able to separate mixtures to remove the pollutant components.

chromatography serves mainly as a tool for the examination and separation of mixtures of chemical substances. the chromatographic sequence of sorbed substances is related to their atomic and molecular structures. for a particular mixture, the solvent and the paper must be chosen so the solubility is reversible and be selective for the components of the mixture. next, you hang a thin strip of filter paper on the hooked end of the paper clip. the paper should not touch the sides of the test tube and should almost touch the bottom of the test tube. put the filter paper back into the test tube with the bottom of the paper in the water and the black band above the water.
when the solvent has reached the pencil line, remove the paper from the test tube. calculate a ratio for each color by dividing the distance the color traveled by the distance the solvent traveled. as the solvent traveled up the paper, which color of ink appeared first? the inks separated because the black ink was a mixture of different pigments with different molecular characteristics. another color may have been present, but not detected because of the filter paper length. the black ink gets its color from a mixture of various colored inks blended together.
