    A suitable column would probably be something like Agilent J&W DB-FFAP (30 m 320 μm, 0.25 μm) which has been used successfully to separate formic acid from acetic acid, as for the separation method what do you mean you have already specified you will be using GC. Do you mean the temperature program? That will depend on your concentrations and experimental set up, you just try different temperatures and ramp rates until you get a program that gives good separation, there isn't really a shortcut to determine this.

    Hope this helps.
