Why Must The Spot Applied To A Tlc Plate Be Above The Developing Solvent. As a general rule of thumb: Thin layer chromatography (tlc) is a powerful technique to separate compounds, based upon their polarity and interaction with silica, and to assess the purifty of a sample. If the plate enters the solvent at an angle, it will cause a slanted solvent front line. If not, parts of the plate will overdevelop, and we will get. If the solvent level in the developing jar is deeper than the origin (spotting line) of the tlc plate, the solvent will dissolve the compounds into the. Place a small amount of solvent (= mobile phase) in the container. Developing a plate a tlc plate can be developed in a beaker or closed jar (see picture below). The tlc plate is placed into the developing chamber, and care is taken to make sure that the bottom edge of the plate is perpendicular to the solvent. If the solvent level covers the sample, the sample spot will be washed off into the solvent before it travels up the tlc plate. The sample should be above the solvent level. When the plate is first placed inside the developing chamber, its bottom should be as parallel as possible with the solvent level. As the solvent polarity increases, the rate at which a compound travels up the tlc plate also increases.
