  • Scientific
  • If you wanted to get really properly scientific with this one, you would suspend the paper from the jar lid, so that it was not touching the sides, or the bottom of the jar. (blogspot.com)
  • molecules
  • The salt solution will start to move up the paper as well as the dye molecules, depending on how they react with the solution. (coursehero.com)
  • dyes
  • Each different DYE in the ink will move up the paper at a DIFFERENT rate so the dyes will SEPARATE OUT. (getrevising.co.uk)
  • Using 5 standard dyes and 3 of the 4 papers, I placed a spot of each dye on the lines drawn, and then placed the papers together in the NaCl solution. (coursehero.com)
  • adhesion
  • The attraction of the water to the paper (adhesion force) is larger than the attraction of the water to itself (cohesion force), hence the water moves up the paper. (sciencebuddies.org)
  • Type
  • Research Paper Inclusion is a type of teaching that is being researched by many school districts across the country. (bartleby.com)
  • pencil
  • Rule a pencil line across the strip of paper, 20 mm from the pointed tip. (prezi.com)
  • 5. Next, transfer the pigment extract by spotting onto the centre of the pencil line of a chromatography strip using the head of a small pin as a dropper. (prezi.com)
  • Why do we use pencil instead of pen for the baseline on the filter paper? (getrevising.co.uk)
  • I then drew a 1-inch pencil line from the bottom of each paper. (coursehero.com)
  • observations
  • The first true chromatography is usually attributed to the Russian-Italian botanist Mikhail Tsvet.Tsvet applied his observations with filter paper extraction to the new methods of column fractionation that had been developed in the 1980s for separating the components of petroleum. (prezi.com)
  • uses
  • You can find out more about the science and uses of chromatography at www.sciencebuddies.org/mentoring/project_ideas/Chem_p008.shtml Or, you can just add a few pipe cleaners to make butterflies, and move on from science to art. (blogspot.com)
  • Chromatography that uses selective adsorption on a strip of paper. (lexic.us)
  • different
  • The objective of this project is to compare different chromatography substrates and solvents to see which combination performs best for separating ink components. (sciencebuddies.org)
  • The ink will also be attracted to the paper, to itself, and to the water differently, and thus a different component will move a different distance depending upon the strength of attraction to each of these objects. (sciencebuddies.org)
  • Smooth
  • The 320 paper provides a smooth and uniform texture assuring continuous contact of buffer from the chamber through the gel and transfer membrane to the opposite pole or weight. (rosesci.com)
