The best sources for finding a place to start on these sorts of things are the column-manufacturer's websites. Restek will allow you to enter your analytes and the search engine will find the best hit for you.

I will tell you that formaldehyde will be a tough one unless you have a methanizer or you derivatize it somehow. It's not very heavy and doesn't burn well in a flame.
