Science Buddies: "Ask an Expert"

I am working on my science fair research and I was looking for information regarding paper chromatography. The only information I found was about how the process works and the different steps of the process.i was wondering what i should recolrd because my project is due Feburary 8th.please help me!!!!
Thanks

Hi,

Here are some Science Buddy Project Ideas on chromatography:

Both these ideas suggest measuring the relative response factor (Rf), which is how fast your spot migrates relative to the solvent front. Additionally you might want to see how Rf varies when you change the solvent, and to measure the Rf of each component of your sample.

This is a great experiment exploring one of the most frequently used analytical techniques in chemistry.

If you have questions about how to do a science fair project check ut the Science Buddies Project Guide:

Good luck and have fun with it!

Thank you soooooo much i really appreciate it. I just have one more question. Im doing the project on science buddies called Reveal the Red:exploring the chemistry of red flower pigments. I need the special chromatography paper. Where else could i find some that is farely inexpensive besides the internet? I was also wondering if coffee filters would work?

Hi

Here is Science Buddies advice on picking a chromatography paper with advice on where to get it:

They advise against using coffee filters.

Thanks I might end up using paper towels if i cant find the chromatography paper for cheap.
