Chemical separation on a GC instrument

Given: 1. GC instrument 2. polysiloxane column 3. 1mM solution of each of the following compunds in methanol.

Compounds divided into 3 separate groups:

1. Carboxylic Acid:
a. benzoic acid b. Phthalic acid c. Toluic acid

2. Amino:
a. aniline b. 4-aminotoluene c. ortho-
pheylenediamine

3. Amino Carboxylic Acids:
a. 4-aminobenzoic acid b. 2-aminobenzoic acid c.
4-amino-2-methylbenzoic acid

I need a suggestion on the best temperature parameters to get good separation for each separate group. Any ideas?
