Separation of Pen Ink?

You guys ever wonder how to separate the mixture of your pen ink? Well, I got the answer with me. Well, the method would be chromatography. Wanna know how?

1. Put a dot of ink around 1/4 of the way up a piece of filter paper.

2. Place the filter paper in a buffer solution but don't submerge the dot of ink.

3. Wait for the buffer solution to get most of the way up the filter paper via absorption

4. Finally, the ink should have separated into different colours that moved different distances up the filter paper.
