What could cause poor separation (such as streaking) in thin-layer chromatography of pen ink dyes?
Homework Answers
Streaking is caused in thin layer chromatography of pen ink dyes because of the following reasons:
- Very high concentration of the sample spot prohibits the substance from travelling as a single separated spot and thus they travel as streak.
- Sometimes the solvent level covers the sample that causes the sample spot to be washed off.
Also keep in mind that Streaking can be eliminated by making the sample solution more dilute.

1. What is the origin of the colors of the ink in the pens? Is the ink made up of several dyes or just one? How do the colors of the dyes which are used result in the color of the ink which we observe? This question is from our chromatography lab where we saw the different color dyes in each pen. I know it has to do with their polarity, but I'm not sure why the different colored dyes...
