Elution Order - cis/trans-1,4-dichloro-2-butene
Posted: Mon Oct 15, 2007 4:46 am
Hi,
I am running a P&T GC/MS for Volatile compounds using an Agilent DB-VRX column 20x0.180x1.00 and I am confused on the elution order of the 1,4-dichloro-2-butene isomers. I was of the understanding that cis eluted before trans, however a recent elution order released by Agilent shows trans before cis. Agilent is currently trying to help me and have told me to inject the standards myself to be certain. I can't justify the expense of buying the seperate standards so I was wondering if there is anyone with first hand evidence of the elution order.
Cheers
