Column Documentation

Here will be Column Documentation.

Here I need the most help.

I am seeking to find the best DIY possibilities here. Self-packing, simple but good separation, of basic organic short-chain molecules. I think this offers the best opportunities for education and ease of sample prep and method development at this point.

Please post any replies/comments you feel appropriate. I am open to any/all suggestions/advice.
