Best column to use for ASTM 2425?

Hi,

I'm looking to setup my Varian GC/MS for ASTM 2425 to test for cycloparaffins and aromatics. Any suggestions?

You realize this is a direct MS method? Not written as a GCMS method. The fractionation occurs with the manual pre-column.

Best regards,

I have never performed a direct MS analysis. I'm currently setup on a Varian CP-3800 and Saturn 2200 MS. Would I be able to setup my current system for ASTM 2425?
