Hi.

I recommend you check out the book " Biodiesel science and technology From soil to oil" for detailed information on transesterification catalysts.

In a very simple way, it will depend on the acid content of your oil and the yield you desire. Because you want to analyse the oil, I'm guessing you want to esterify everything, so although slower, an acid process will be more suitable if the acid content of the oil is fairly high.

Cheers!
