Which analytical technique????????

Feb 2012
Hi there,

I am working on cardon dioxide reduction and need to identify and quantify the products, I don't know exactly what will be in the reduced solution. But, most probably the solution will contain tiny amounts of :

methanol, formic acid,methane and formaldehyde in aqueous phase, I also expect the reactants to be present in small amounts: The reactants are acetate, KCl and pyridine in deionised water at PH=5.2.

Which analytical technique (s) is suitable in this case to both identify and quantify the mentionable compounds? Do I need to

Can anyone help me with this please?

Thank you in advance.
