ink spots - 2step 1draw a line near the bottom of the sheet of filter paper and add spots of ink to the line
- 3step 2put it in the solvent and make sure the ink isn't touching the solvent
- 4step 3place a lid on the container to stop the solvent evaporating, as the solvent seeps up the paper it will carry the ink with it and each dye in the ink will move up the paper at different rates so the dyes will separate out and form a sport in a different place (one sport per dye in ink)
- 5step 4is any of the dyes in the ink are insoluble they will stay one the baseline
- 6step 5when the solvent has almost reached the top of the paper take it out and dry it the end result is called a chromatogram
