Homework Help: Why during chromatography must the paper NOT touch the sides

  1. Nov 28, 2011 #1
    1. The problem statement, all variables and given/known data
    why during chromatography must the paper NOT touch the sides of the test tubes in which the experiment is being carried out?



    2. Relevant equations



    3. The attempt at a solution
    I am not sure but could our results get smudged or distroted?
    if so I still can't work out how? could it be that the solvent does not run in a straight line :S

    Re: Chromotrography

    What might happen if the glass wall started wicking solvent from the chromatogram during the experiment?
