2. Different marker inks were analyzed using a simple paper chromatography
experiment. Two marker inks were dissolved separately in a solvent and spotted
in the chromatogram. The mobile phase used was 1% NaCl and three ink
standards (A-copper-phthalocyanine blue, B-diarylide yellow,C- lithol rubine red)
were spotted beside the two sample markers. After the chromatography, the
chromatogram showed a separation of colors in the two inks (D and E).
