Chromatogrophy

Chromatography is greek for Colour Picture

Aim: To sperate different pigments in inks or dye using paper Chromatography

Equipment: Filter Paper, Felt Pens x2, 250 mL, Mr Stock's Chromatography solvent

Method: Method:

1. Cut a strip of filter paper.
2. Rule a line about 2cm from the bottom (a straight line) or do your finger width.
3. Grab your felt pen and do a dark circle until you feel like you nearly just coloured the paper.
4. Fill your beaker up to 1cm
5. Dip your paper in slowly and when it hits the line just leave it there. ( Tape the bit you are up to.)
6. And then see the magic happen.

Observations:

When I dipped the paper in I saw what happened to it. It slowly moved the felt up or kept the felt dot in one place and the rest went up.

It depends on what colour you are doing for e.g my colours were orange and green.  As you can see by the picture the green separated into a lighter green and blue and climbed the paper whereas the orange didn't separate but still climbed the paper
